This may be obvious to some participants but it +doesn't harm to preach to the choir. + +Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people's code to run), they +often don't know or use good practices when it comes to recording dependencies. +Most participants also don't use isolated environments for different projects and +don't know why that can be important. +The episode "Recording dependencies" tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager. + +Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +"Recording environments" introduces the concept of containers, and the optional +episode "Creating and sharing a container image" goes into details. + +Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of "scientific workflows", +and that there actually exist tools that help make such workflows reproducible. +The episode "Recording computational steps" introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible. + + +## How to teach this lesson + +### How to start + +Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this.

This may be obvious to some participants but it +doesn't harm to preach to the choir. + +Many participants do not share data or code, and in particular they are often +unaware that research output other than published articles can be assigned +digital object identifiers (DOIs). +The "Sharing code and data" is meant to bring awareness about FAIRness and Open Science +and to show how DOIs can be obtained for Git repositories.. + +Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people's code to run), they +often don't know or use good practices when it comes to recording dependencies. +Most participants also don't use isolated environments for different projects and +don't know why that can be important. +The episode "Recording dependencies" tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager. + +Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +"Recording environments" introduces the concept of containers, and the optional +episode "Creating and sharing a container image" goes into details. + +Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of "scientific workflows", +and that there actually exist tools that help make such workflows reproducible. +The episode "Recording computational steps" introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible. + + +## How to teach this lesson + +### How to start + +Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we're going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers). + + +### Focus on concepts, and when to use which tool + +Try to explain better what the different tools are useful for, but don't go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem. + + +## Typical pitfalls + +#### Indentation in Snakefiles + +- the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn't matter +This works: +```python +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` +but this doesn't work: +```python +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` +nor this: +```python +rule all: +input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` + + +## Field reports + +### 2022 September + +We used the strategy "absolutely minimal introductions, most time +for exercise". Overall, it was probably the right thing to do since +there is so little time and so much to cover. + +There wasn't enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode. + +The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn't really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day. + +Perhaps we shouldn't have done the Zenodo example - we could do a +quick demo, but because of limited time, I'm not sure if it conveyed +how cool it was.

Rerunning only +part of the steps or only part of the input data requires us to outcomment +lines in our script which can again become tedious and error-prone. +``` +```` + +````{exercise} Workflow-2: Workflow solution using Snakemake + +```{figure} img/snakemake.png +:alt: How Snakemake works +:width: 100% +``` + +Somebody wrote a [Snakemake](https://snakemake.readthedocs.io) solution +and the interesting file here is the [Snakefile](https://github.com/coderefinery/word-count/blob/main/Snakefile): +``` +# a list of all the books we are analyzing +DATA = glob_wildcards('data/{book}.txt').book + +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) + +# count words in one of our books +rule count_words: + input: + script='statistics/count.py', + book='data/{file}.txt' + output: 'statistics/{file}.data' + conda: 'environment.yml' + log: 'statistics/{file}.log' + shell: 'python {input.script} {input.book} > {output}' + +# create a plot for each book +rule make_plot: + input: + script='plot/plot.py', + book='statistics/{file}.data' + output: 'plot/{file}.png' + conda: 'environment.yml' + log: 'plot/{file}.log' + shell: 'python {input.script} --data-file {input.book} --plot-file {output}' +``` + +Snakemake uses **declarative style**: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (`output`) to dependencies +(`input`) and commands (`shell`). + +Exercise goals: +1. Clone the example to your computer: `$ git clone https://github.com/coderefinery/word-count.git` +2. Study the Snakefile. How does it know what to do first and what to do then? +3. Try to run it. Since version 5.11 one needs to specify number of cores (or + jobs) using `-j`, `--jobs` or `--cores`: + ```console + $ snakemake --delete-all-output -j 1 + $ snakemake -j 1 + ``` + The `--delete-all-output` part makes sure that we remove all generated files before we start. +4. Try running `snakemake` again and observe that and discuss why it refused to rerun all steps: + ```console + $ snakemake -j 1 + + Building DAG of jobs... + Nothing to be done (all requested files are present and up to date). + ``` +5. Make a tiny modification to the plot.py script and run `$ snakemake -j 1` again and observe how it will only re-run the plot steps. +6. Make a tiny modification to one of the books and run `$ snakemake -j 1` again and observe how it only regenerates files for this book. +7. Discuss possible advantages compared to a scripted solution. +8. **Question for R developers**: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in + the [Snakefile](https://github.com/coderefinery/word-count/blob/main/Snakefile) would you have to modify so that it uses your R code? +9. If you make changes to the Snakefile, validate it using `$ snakemake --lint`. + +```{solution} +- 2: Start with "all" and look what it depends on. Now search for rules that + have these as output. Look for their inputs and search where they + are produced. In other words, search backwards and build a graph of + dependencies. This is what Snakemake does. +- 4: It can see that outputs are newer than inputs. It will only regenerate + outputs if they are not there or if the inputs or scripts have changed. +- 7: It only generates steps and outputs that are missing or outdated. The workflow + does not run everything every time. In other words if you notice a problem or update information + "half way" in the analysis, it will only re-run what needs to be re-run. Nothing more, nothing less. + Another advantage is that it can distribute tasks to multiple cores, off-load work to supercomputers, + offers more fine-grained control over environments, and more. +- 8: Probably only the two lines containeing "shell". +``` +```` + + +## Why [Snakemake](https://snakemake.readthedocs.io/)? + +- Gentle learning curve. +- Free, open-source, and installs easily via conda or pip. +- Cross-platform (Windows, MacOS, Linux) and compatible with all HPC schedulers: + same workflow works without modification and scales appropriately whether on a laptop or cluster. +- [Heavily used in bioinformatics](https://twitter.com/carl_witt/status/1103951128046301185), but is completely general. +- Is is possible to define isolated software environments per rule, see [here](https://github.com/coderefinery/word-count/blob/f4ca47440751dd2c65f55fef1a8d9f181ecdd2f6/Snakefile#L15). +- Also possible to run workflows in Docker or Apptainer containers. +- Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up. +- If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel. +- Nice functionality for archiving the workflow, see: [the official documentation](https://snakemake.readthedocs.io/en/stable/snakefiles/deployment.html#sustainable-and-reproducible-archiving) + + +## Similar tools + +- [Make](https://www.gnu.org/software/make/) +- [Nextflow](https://www.nextflow.io/) +- [Task](https://taskfile.dev/) +- [Common Workflow Language](https://www.commonwl.org/) +- Many [specialized frameworks](https://github.com/common-workflow-language/common-workflow-language/wiki/Existing-Workflow-systems) exist. + + +## Visualizing the workflow + +We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the `--dag` option, which will output the DAG in `dot` language. + +**Note**: This requires the [Graphviz software](https://www.graphviz.org/), +which can be installed by `conda install graphviz`).

Tools and what problems they try to solve

+

Conda, Anaconda, pip, virtualenv, Pipenv, pyenv, Poetry, requirements.txt, +environment.yml, renv, …, these tools try to solve the following problems:

+
    +

  • Defining a specific set of dependencies, possibly with well defined versions

    • +

  • Installing those dependencies mostly automatically

    • +

  • Recording the versions for all dependencies

    • +

  • Isolate environments

    +
      +

    • On your computer for projects so they can use different software

      • +

    • Isolate environments on computers with many users (and allow self-installations)

      • +
    +
    • +

  • Using different Python/R versions per project

    • +

  • Provide tools and services to share packages

    • +
+

Isolated environments are also useful because they help you make sure +that you know your dependencies!

+

If things go wrong, you can delete and re-create - much better +than debugging. The more often you re-create your environment, the +more reproducible it is.

Exercises

+
+

Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project

+
    +
    +

    D: +You find a environment.yml file with:

Dependencies-2: Create a time-capsule for the future

+

Now it is time to create your own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+
+
+

What is a container?

+

Imagine if you didn’t have to install things yourself, but instead you could +get a computer with the exact software for a task pre-installed? Containers +effectively do that, with various advantages and disadvantages. They are +like an entire operating system with software installed, all in one file,

+
+He said, then we will ship your machine. And that's how Docker was born. +

Kitchen analogy

+
    +

  • Our codes/scripts <-> cooking recipes

    • +

  • Container definition files <-> like a blueprint to build a kitchen with all +utensils in which the recipe can be prepared.

    • +

  • Container images <-> example kitchens

    • +

  • Containers <-> identical factory-built mobile food truck kitchens

    • +
+

Just for fun: which operating systems do the following example kitchens represent?

From definition files to container images to containers

+
    +

  • Containers can be built to bundle all the necessary ingredients (data, code, environment, operating system).

    • +

  • A container image is like a piece of paper with all the operating system on it. When you run it, +a transparent sheet is placed on top to form a container. The container runs and writes only on +that transparent sheet (and what other mounts have been layered on top). When you are done, +transparency is thrown away. It can be repeated as often as you want, and base is always the same.

    • +

  • Definition files (e.g. Dockerfile or Singularity definition file) are text +files that contain a series of instructions to build container images.

    • +
+

Here is an example of a Singularity definition file (reference):

+
Bootstrap: docker
+From: ubuntu:20.04
+
+%post
+    apt-get -y update
+    apt-get -y install cowsay lolcat
+
+%environment
+    export LC_ALL=C
+    export PATH=/usr/games:$PATH
+
+%runscript
+    date | cowsay | lolcat
+
+
+

Popular container implementations:

+ +

They are to some extent interoperable:

+
    +

  • podman is very close to Docker

    • +

  • Docker images can be converted to Singularity/Apptainer images

    • +

  • Singularity Python can convert Dockerfiles to Singularity definition files

    • +
+
+
+
+

Pros and cons of containers

+

Containers are popular for a reason - they solve a number of +important problems:

+
    +

  • Allow for seamlessly moving workflows across different platforms.

    • +

  • Can solve the “works on my machine” situation.

    • +

  • For software with many dependencies, in turn with its own dependencies, +containers offer possibly the only way to preserve the +computational experiment for future reproducibility.

    • +

  • A mechanism to “send the computer to the data” when data is too

    • +

  • Installing software into a file instead of into your computer (removing +a file is often easier than uninstalling software if you suddenly regret an +installation)

    • +
+

However, containers may also have some drawbacks:

+
    +

  • Can be used to hide away software installation problems and thereby +discourage good software development practices.

    • +

  • Instead of “works on my machine” problem: “works only in this container” problem?

    • +

  • They can be difficult to modify (this is the focus of an exercise below)

    • +

  • Container images can become large

    • +
+
+

Danger

+

Use only official and trusted images! Not all images can be trusted! There +have been examples of contaminated images so investigate before using images +blindly. Apply same caution as installing software packages from untrusted +package repositories.

+
+
+
+
+

Where can one share or find images?

+ +
+
+
+

Exercises

+
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash
+
    +

Sharing code and data

In sharing.md:

+
+

Sharing-1: Get a DOI from Zenodo

+

Digital object identifiers (DOI) are the backbone of the academic +reference and metrics system. In this exercise we will see how to +make a GitHub repository citable by archiving it on the +Zenodo archiving service. Zenodo is a +general-purpose open access repository created by OpenAIRE and CERN.

+
    +

  1. Sign in to Zenodo using your GitHub account. For this exercise, use the +sandbox service: https://sandbox.zenodo.org/login/. This is a test version of the real Zenodo platform.

    2. +

  2. Go to https://sandbox.zenodo.org/account/settings/github/.

    3. +

  3. Find the repository you wish to publish, +and flip the switch to ON.

    4. +

  4. Go to GitHub and create a release by clicking the Create a new release on the +right-hand side (a release is based on a Git tag, but is a higher-level GitHub feature). +You will need to enter a tag name (e.g. v0.1) in the “Choose a tag” box.

    5. +

  5. Creating a new release will trigger Zenodo into archiving your repository, +and a DOI badge will be displayed next to your repository after a minute +or two. You can include it in your GitHub README file: click the +DOI badge and copy the relevant format (Markdown, RST, HTML).

Detailed day schedule

+

This was the schedule at our last workshop:

+ +
+
+

Why we teach this lesson

+

Reproducibility in research is something that publishers, funding agencies, universities, +research leaders and the general public worries about and much is being written about it. +It is also something that researchers care deeply about - this lesson is typically one of the +most popular lessons in the pre-workshop survey.

+

Even though most PhD students, postdocs and researchers (i.e. typical workshop participants) +know about the importance of reproducibility in research, they often lack both a general +overview of what different aspects there are to reproducibility, and the knowledge of +specific tools that can be used for improving reproducibility.

+

Many participants may not adhere to good practices when organizing their projects, +and the “Organizing your projects” episode is meant to encourage participants to +structure their projects better. This may be obvious to some participants but it +doesn’t harm to preach to the choir.

+

Many participants do not share data or code, and in particular they are often +unaware that research output other than published articles can be assigned +digital object identifiers (DOIs). +The “Sharing code and data” is meant to bring awareness about FAIRness and Open Science +and to show how DOIs can be obtained for Git repositories..

+

Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people’s code to run), they +often don’t know or use good practices when it comes to recording dependencies. +Most participants also don’t use isolated environments for different projects and +don’t know why that can be important. +The episode “Recording dependencies” tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager.

+

Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +“Recording environments” introduces the concept of containers, and the optional +episode “Creating and sharing a container image” goes into details.

+

Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of “scientific workflows”, +and that there actually exist tools that help make such workflows reproducible. +The episode “Recording computational steps” introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible.

+
+
+

How to teach this lesson

+
+

How to start

+

Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we’re going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers).

+
+
+

Focus on concepts, and when to use which tool

+

Try to explain better what the different tools are useful for, but don’t go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem.

+
+
+
+

Typical pitfalls

+
+

Indentation in Snakefiles

+
    +

  • the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn’t matter +This works:

    • +
+
rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+
+

but this doesn’t work:

+
rule all:
+    input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+

nor this:

+
rule all:
+input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+
+
+
+

Field reports

+
+

2022 September

+

We used the strategy “absolutely minimal introductions, most time +for exercise”. Overall, it was probably the right thing to do since +there is so little time and so much to cover.

+

There wasn’t enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode.

+

The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn’t really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day.

+

Perhaps we shouldn’t have done the Zenodo example - we could do a +quick demo, but because of limited time, I’m not sure if it conveyed +how cool it was. Maybe we should have simply said it. Alternatively, +we could have not done the Docker demonstration and given more time +for Zenodo.

Reproducible research

+

Have you ever spent days trying to repeat the results from few weeks or months +ago? Or you have to do paper revisions, but you just can’t get the results to +match up? It’s unpleasant for both you and science.

+

In this lesson we will explore different methods and tools for better +reproducibility in research software and data. We will demonstrate how version +control, workflows, containers, and package managers can be used to record +reproducible environments and computational steps for our future selves.

+
+

A scary anecdote

+
    +

  • A group of researchers obtain great results and submit their work to a high-profile journal.

    • +

  • Reviewers ask for new figures and additional analysis.

    • +

  • The researchers start working on revisions and generate modified figures, but find inconsistencies with old figures.

    • +

  • The researchers can’t find some of the data they used to generate the original results, and +can’t figure out which parameters they used when running their analyses.

    • +

  • The manuscript is still languishing in the drawer …

    • +
+
+
+
+

Why talking about reproducible research?

+

A 2016 +survey +in Nature revealed that irreproducible experiments are a problem across all +domains of science:

+
+reproduciblity Nature +
+

This study is now few years old but the highlighted problem did not get +smaller.

+
+
+
+

Levels of reproducibility

+

A published article is like the top of a pyramid. It rests on multiple +levels that each contributes to its reproducibility.

Organizing your projects

+
+

Objectives

+
    +

  • Get an overview on how to organize research projects

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching incl. discussions

    • +
+
+

One of the most basic steps to make your work reproducible is to organize your projects well. +Let’s go over some of the basic things which people have found to work (and not to work).

+
+

Directory structure for projects

+
    +

  • Project files in a single folder

    • +

  • Different projects should have separate folders

    • +

  • Use consistent and informative directory structure

    +
      +

    • Avoid spaces in directory and file names – it is uglier for humans but handy for computers.

      • +
    +
    • +

  • If you need to separate public/private, you can put them in public and private Git repos

    +
      +

    • If you need to separate public/secret, use .gitignore or a separate folder that’s not in Git

      • +
    +
    • +

  • Add a README file to describe the project and instructions on reproducing the results

    • +

  • If a software is reused in several projects it can make sense to put them in own repo

    • +
+

A project directory can look something like this:

+
project_name/
+├── README.md             # overview of the project
+├── data/                 # data files used in the project
+│   ├── README.md         # describes where data came from
+│   └── sub-folder/       # may contain subdirectories
+├── processed_data/       # intermediate files from the analysis
+├── manuscript/           # manuscript describing the results
+├── results/              # results of the analysis (data, tables, figures)
+├── src/                  # contains all code in the project
+│   ├── LICENSE           # license for your code
+│   ├── requirements.txt  # software requirements and dependencies
+│   └── ...
+└── doc/                  # documentation for your project
+    ├── index.rst
+    └── ...
+
+
+
+
+
+

Tracking source code, data, and results

+
    +

  • All code is version controlled and goes in the src/ or source/ directory

    • +

  • Include appropriate LICENSE file and information on software requirements

    • +

  • You can also version control data files or input files under data/

    • +

  • If data files are too large (or sensitive) to track, untrack them using .gitignore

    • +

  • Intermediate files from the analysis are kept in processed_data/

    • +

  • Consider using Git tags to mark specific versions of results (version +submitted to a journal, dissertation version, poster version, etc.):

    +
    $ git tag -a thesis-submitted -m "this is the submitted version of my thesis"
+
    +
    +
    • +
+ +
+
+
+

Reproducible publications

+
    +

  • Git can be used to collaborate on manuscripts written in, e.g., LaTeX and other text-based formats but other tools exist:

    +
      +

    • Overleaf: an online, collaborative LaTeX editor (has Git integration)

      • +

    • Authorea: collaborative platform for preprints (apparently also has Git integration)

      • +

    • HackMD: an online collaborative Markdown editor (has Git integration)

      • +

    • Manuscripts.io: a collaborative authoring tool that support scientific content and reproducibility.

      • +

    • Google Docs can be a good alternative

      • +
    +
    • +

  • Many tools exist to assist in making scholarly output reproducible:

    +
      +

    • rrtools: instructions, templates, and functions for writing a reproducible article or report with R.

      • +

    • Jupyter Notebooks: web-based computational environment for creating code and text based notebooks that can be used as +supplementary material for articles.

      • +

    • Binder: makes a repository with Jupyter notebooks available in an executable environment (discussed later in the Jupyter lesson).

      • +

    • “Research compendia”: a set of good practices for +reproducible data analysis in R, but much is transferable to other languages.

Sharing research data

+

The Open Science movement encourages researchers +to share research output beyond the contents of a +published academic article (and possibly supplementary information).

+
+Research comic +
+

Arguments in favor (from Wikipedia):

+
    +

  • Open access publication of research reports and data allows for rigorous peer-review

    • +

  • Science is publicly funded so all results of the research should be publicly available

    • +

  • Open Science will make science more reproducible and transparent

    • +

  • Open Science has more impact

    • +

  • Open Science will help answer uniquely complex questions

    • +
+

Arguments against (from Wikipedia):

+
    +

  • Too much unsorted information overwhelms scientists

    • +

  • Potential misuse

    • +

  • The public will misunderstand science data

    • +

  • Increasing the scale of science will make verification of any discovery more difficult

    • +

  • Low-quality science

FAIR principles

+
+Research comic +
+

(This image was created by Scriberia for The +Turing Way community and is used under a +CC-BY licence. The image was obtained from https://zenodo.org/record/3332808.)

+

“FAIR” is the current buzzword for data management. You may be asked +about it in, for example, making data management plans for grants:

+
    +

  • Findable

    +
      +

    • Will anyone else know that your data exists?

      • +

    • Solutions: put it in a standard repository, or at least a +description of the data. Get a digital object identifier (DOI).

      • +
    +
    • +

  • Accessible

    +
      +

    • Once someone knows that the data exists, can they get it?

      • +

    • Usually solved by being in a repository, but for non-open data, +may require more procedures.

      • +
    +
    • +

  • Interoperable

Exercise - Connecting repositories to Zenodo

+
+

Sharing-1: Get a DOI from Zenodo

+

Digital object identifiers (DOI) are the backbone of the academic +reference and metrics system. In this exercise we will see how to +make a GitHub repository citable by archiving it on the +Zenodo archiving service. Zenodo is a +general-purpose open access repository created by OpenAIRE and CERN.

+
    +

  1. Sign in to Zenodo using your GitHub account. For this exercise, use the +sandbox service: https://sandbox.zenodo.org/login/. This is a test version of the real Zenodo platform.

    2. +

  2. Go to https://sandbox.zenodo.org/account/settings/github/.

    3. +

  3. Find the repository you wish to publish, +and flip the switch to ON.

    4. +

  4. Go to GitHub and create a release by clicking the Create a new release on the +right-hand side (a release is based on a Git tag, but is a higher-level GitHub feature). +You will need to enter a tag name (e.g. v0.1) in the “Choose a tag” box.

    5. +

  5. Creating a new release will trigger Zenodo into archiving your repository, +and a DOI badge will be displayed next to your repository after a minute +or two. You can include it in your GitHub README file: click the +DOI badge and copy the relevant format (Markdown, RST, HTML).

    6. +
+
+
+
+
+

Services for sharing and collaborating on research data

+

To find a research data repository for your data, you can search on the +Registry of Research Data Repositories (re3data) +platform and filter by country, content type, discipline, etc.

+

International:

+
    +

  • Zenodo: A general-purpose open access repository +created by OpenAIRE and CERN. Integration with GitHub, allows +researchers to upload files up to 50 GB.

    • +

  • Figshare: Online digital repository where researchers +can preserve and share their research outputs (figures, datasets, images and videos). +Users can make all of their research outputs available in a citable, +shareable and discoverable manner.

    • +

  • EUDAT: European platform for researchers and practitioners from any research discipline to preserve, find, access, and process data in a trusted environment.

    • +

Recording computational steps

+
+

Questions

+
    +

  • You have some steps that need to be run to do your work. How do you +actually run them? Does it rely on your own memory and work, or is it +reproducible? How do you communicate the steps for future you and others?

    • +

  • How can we create a reproducible workflow?

    • +

  • When to use scientific workflow management systems.

Several steps from input data to result

+

The following material is partly derived from a HPC Carpentry lesson.

+

In this episode, we will use an example +project which finds most frequent +words in books and plots the result from those statistics. In this example we +wish to:

+
    +

  1. Analyze word frequencies using statistics/count.py +for 4 books +(they are all in the data directory).

    2. +

  2. Plot a histogram using plot/plot.py.

    3. +
+
+From book to word counts to plot +
+

Example (for one book only):

+
$ python statistics/count.py data/isles.txt > statistics/isles.data
+$ python plot/plot.py --data-file statistics/isles.data --plot-file plot/isles.png
+
+
+
+

Discussion

+

We have two steps and 4 books. But imagine having 4 steps and processing 500 books. +Can you relate? Are you using similar setups in your research? How do you record them?

+
+
+

Kitchen analogy

+
+Busy kitchen +
+

Now we have many similar meals to prepare and possibly many chefs +present (cores) and workflow tools can help us to plan and document the steps +and run them efficiently. [Midjourney, CC-BY-NC 4.0]

+

Exercise

+
+

Exercise preparation

+

The exercise (below) and pre-exercise discussion uses a simple +word-count repository +(https://github.com/coderefinery/word-count). We should clone the +repository already to prepare to work on it.

+

You could do the exercise either on your own computer, or the Binder +cloud service:

+

On your own computer:

+
    +

  • Activate the coderefinery conda environment with conda activate coderefinery.

    • +

  • Clone the word-count repository:

    +
    $ git clone https://github.com/coderefinery/word-count.git
+
    +
    +
    • +
+

On Binder: +We can also use the cloud service Binder to make sure +we all have the same computing environment. This is interesting from a +reproducible research point of view and it’s explained further in the Jupyter +lesson how this is even +possible.

+
    +

  • Go to https://github.com/coderefinery/word-count and click on the “launch binder” badge in the README.

    • +

  • Once it get started, you can open a new Terminal from the new menu (top right) and select Terminal.

    • +
+
+
+

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

    • +
+ +
+
+

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

    10. +
+ +
+
+
+

Why Snakemake?

+
    +

  • Gentle learning curve.

    • +

  • Free, open-source, and installs easily via conda or pip.

    • +

  • Cross-platform (Windows, MacOS, Linux) and compatible with all HPC schedulers: +same workflow works without modification and scales appropriately whether on a laptop or cluster.

    • +

  • Heavily used in bioinformatics, but is completely general.

    • +

  • Is is possible to define isolated software environments per rule, see here.

    • +

  • Also possible to run workflows in Docker or Apptainer containers.

    • +

  • Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up.

    • +

  • If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel.

    • +

  • Nice functionality for archiving the workflow, see: the official documentation

    • +
+
+
+

Similar tools

+ +
+
+

Visualizing the workflow

+

We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the --dag option, which will output the DAG in dot language.

+

Note: This requires the Graphviz software, +which can be installed by conda install graphviz). It’s not necessary to +run this step yourself.

+
$ snakemake -j 1 --dag | dot -Tpng > dag.png
+
+
+

Rules that have yet to be completed are indicated with solid outlines, while already completed rules are indicated with dashed outlines.

This may be obvious to some participants but it +doesn't harm to preach to the choir. + +Many participants do not share data or code, and in particular they are often +unaware that research output other than published articles can be assigned +digital object identifiers (DOIs). +The "Sharing code and data" is meant to bring awareness about FAIRness and Open Science +and to show how DOIs can be obtained for Git repositories.. + +Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people's code to run), they +often don't know or use good practices when it comes to recording dependencies. +Most participants also don't use isolated environments for different projects and +don't know why that can be important. +The episode "Recording dependencies" tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager. + +Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +"Recording environments" introduces the concept of containers, and the optional +episode "Creating and sharing a container image" goes into details. + +Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of "scientific workflows", +and that there actually exist tools that help make such workflows reproducible. +The episode "Recording computational steps" introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible. + + +## How to teach this lesson + +### How to start + +Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we're going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers). + + +### Focus on concepts, and when to use which tool + +Try to explain better what the different tools are useful for, but don't go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem. + + +## Typical pitfalls + +### Indentation in Snakefiles + +- the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn't matter +This works: +```python +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` +but this doesn't work: +```python +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` +nor this: +```python +rule all: +input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` + + +## Field reports + +### 2022 September + +We used the strategy "absolutely minimal introductions, most time +for exercise". Overall, it was probably the right thing to do since +there is so little time and so much to cover. + +There wasn't enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode. + +The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn't really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day. + +Perhaps we shouldn't have done the Zenodo example - we could do a +quick demo, but because of limited time, I'm not sure if it conveyed +how cool it was.

What problems do you anticipate + with a scripted solution? + +```{solution} +The advantage of this solution compared to processing one by one is more automation: We can generate all. +This is not only easier, it is also less error-prone. + +Yes, the scripted solution can be reproducible. + +If we had more steps and once steps start to be time-consuming, a limitation of +a scripted solution is that it tries to run all steps always. Rerunning only +part of the steps or only part of the input data requires us to outcomment +lines in our script which can again become tedious and error-prone. +``` +```` + +````{exercise} Workflow-2: Workflow solution using Snakemake + +```{figure} img/snakemake.png +:alt: How Snakemake works +:width: 100% +``` + +Somebody wrote a [Snakemake](https://snakemake.readthedocs.io) solution +and the interesting file here is the [Snakefile](https://github.com/coderefinery/word-count/blob/main/Snakefile): +``` +# a list of all the books we are analyzing +DATA = glob_wildcards('data/{book}.txt').book + +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) + +# count words in one of our books +rule count_words: + input: + script='statistics/count.py', + book='data/{file}.txt' + output: 'statistics/{file}.data' + conda: 'environment.yml' + log: 'statistics/{file}.log' + shell: 'python {input.script} {input.book} > {output}' + +# create a plot for each book +rule make_plot: + input: + script='plot/plot.py', + book='statistics/{file}.data' + output: 'plot/{file}.png' + conda: 'environment.yml' + log: 'plot/{file}.log' + shell: 'python {input.script} --data-file {input.book} --plot-file {output}' +``` + +Snakemake uses **declarative style**: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (`output`) to dependencies +(`input`) and commands (`shell`). + +Exercise goals: +1. Clone the example to your computer: `$ git clone https://github.com/coderefinery/word-count.git` +2. Study the Snakefile. How does it know what to do first and what to do then? +3. Try to run it. Since version 5.11 one needs to specify number of cores (or + jobs) using `-j`, `--jobs` or `--cores`: + ```console + $ snakemake --delete-all-output -j 1 + $ snakemake -j 1 + ``` + The `--delete-all-output` part makes sure that we remove all generated files before we start. +4. Try running `snakemake` again and observe that and discuss why it refused to rerun all steps: + ```console + $ snakemake -j 1 + + Building DAG of jobs... + Nothing to be done (all requested files are present and up to date). + ``` +5. Make a tiny modification to the plot.py script and run `$ snakemake -j 1` again and observe how it will only re-run the plot steps. +6. Make a tiny modification to one of the books and run `$ snakemake -j 1` again and observe how it only regenerates files for this book. +7. Discuss possible advantages compared to a scripted solution. +8. **Question for R developers**: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in + the [Snakefile](https://github.com/coderefinery/word-count/blob/main/Snakefile) would you have to modify so that it uses your R code? +9. If you make changes to the Snakefile, validate it using `$ snakemake --lint`. + +```{solution} +- 2: Start with "all" and look what it depends on. Now search for rules that + have these as output. Look for their inputs and search where they + are produced. In other words, search backwards and build a graph of + dependencies. This is what Snakemake does. +- 4: It can see that outputs are newer than inputs. It will only regenerate + outputs if they are not there or if the inputs or scripts have changed. +- 7: It only generates steps and outputs that are missing or outdated. The workflow + does not run everything every time. In other words if you notice a problem or update information + "half way" in the analysis, it will only re-run what needs to be re-run. Nothing more, nothing less. + Another advantage is that it can distribute tasks to multiple cores, off-load work to supercomputers, + offers more fine-grained control over environments, and more. +- 8: Probably only the two lines containeing "shell". +``` +```` + + +## Why [Snakemake](https://snakemake.readthedocs.io/)? + +- Gentle learning curve. +- Free, open-source, and installs easily via conda or pip. +- Cross-platform (Windows, MacOS, Linux) and compatible with all HPC schedulers: + same workflow works without modification and scales appropriately whether on a laptop or cluster. +- [Heavily used in bioinformatics](https://twitter.com/carl_witt/status/1103951128046301185), but is completely general. +- Is is possible to define isolated software environments per rule, see [here](https://github.com/coderefinery/word-count/blob/f4ca47440751dd2c65f55fef1a8d9f181ecdd2f6/Snakefile#L15). +- Also possible to run workflows in Docker or Apptainer containers. +- Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up. +- If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel. +- Nice functionality for archiving the workflow, see: [the official documentation](https://snakemake.readthedocs.io/en/stable/snakefiles/deployment.html#sustainable-and-reproducible-archiving) + + +## Similar tools + +- [Make](https://www.gnu.org/software/make/) +- [Nextflow](https://www.nextflow.io/) +- [Task](https://taskfile.dev/) +- [Common Workflow Language](https://www.commonwl.org/) +- Many [specialized frameworks](https://github.com/common-workflow-language/common-workflow-language/wiki/Existing-Workflow-systems) exist. + + +## Visualizing the workflow + +We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the `--dag` option, which will output the DAG in `dot` language. + +**Note**: This requires the [Graphviz software](https://www.graphviz.org/), +which can be installed by `conda install graphviz`.

Tools and what problems they try to solve

+

Conda, Anaconda, pip, virtualenv, Pipenv, pyenv, Poetry, requirements.txt, +environment.yml, renv, …, these tools try to solve the following problems:

+
    +

  • Defining a specific set of dependencies, possibly with well defined versions

    • +

  • Installing those dependencies mostly automatically

    • +

  • Recording the versions for all dependencies

    • +

  • Isolate environments

    +
      +

    • On your computer for projects so they can use different software

      • +

    • Isolate environments on computers with many users (and allow self-installations)

      • +
    +
    • +

  • Using different Python/R versions per project

    • +

  • Provide tools and services to share packages

    • +
+

Isolated environments are also useful because they help you make sure +that you know your dependencies!

+

If things go wrong, you can delete and re-create - much better +than debugging. The more often you re-create your environment, the +more reproducible it is.

+

Exercises

+
+

(optional) Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click
+  - python
+  - pip
+  - pip:
+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4
+  - sympy=1.4
+  - click=7.0
+  - python=3.8
+  - pip
+  - pip:
+    - git+https://github.com/someuser/someproject.git@d7b2c7e
+    - git+https://github.com/anotheruser/anotherproject.git@sometag
+
    +
    +

    E: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4
+  - sympy=1.4
+  - click=7.0

+  - someproject=1.2.3
+  - anotherproject=2.3.4
+
    +
    +
    + +
    • +
+
+
+

(optional) Dependencies-2: Create a time-capsule for the future

+

Now it is time to create your own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+
+
+

What is a container?

+

Imagine if you didn’t have to install things yourself, but instead you could +get a computer with the exact software for a task pre-installed? Containers +effectively do that, with various advantages and disadvantages. They are +like an entire operating system with software installed, all in one file,

+He said, then we will ship your machine. And that's how Docker was born. +

Kitchen analogy

    +

  • Our codes/scripts <-> cooking recipes

    • +

  • Container definition files <-> like a blueprint to build a kitchen with all +utensils in which the recipe can be prepared.

    • +

  • Container images <-> example kitchens

    • +

  • Containers <-> identical factory-built mobile food truck kitchens

    • +
+

Just for fun: which operating systems do the following example kitchens represent?

From definition files to container images to containers

+
    +

  • Containers can be built to bundle all the necessary ingredients (data, code, environment, operating system).

    • +

  • A container image is like a piece of paper with all the operating system on it. When you run it, +a transparent sheet is placed on top to form a container. The container runs and writes only on +that transparent sheet (and what other mounts have been layered on top). When you are done, +transparency is thrown away. It can be repeated as often as you want, and base is always the same.

    • +

  • Definition files (e.g. Dockerfile or Singularity definition file) are text +files that contain a series of instructions to build container images.

    • +
+

Here is an example of a Singularity definition file (reference):

+
Bootstrap: docker
+From: ubuntu:20.04
+
+%post
+    apt-get -y update
+    apt-get -y install cowsay lolcat
+
+%environment
+    export LC_ALL=C
+    export PATH=/usr/games:$PATH
+
+%runscript
+    date | cowsay | lolcat
+
+
+

Popular container implementations:

+ +

They are to some extent interoperable:

+
    +

  • podman is very close to Docker

    • +

  • Docker images can be converted to Singularity/Apptainer images

    • +

  • Singularity Python can convert Dockerfiles to Singularity definition files

    • +
+
+
+
+

Pros and cons of containers

+

Containers are popular for a reason - they solve a number of +important problems:

+
    +

  • Allow for seamlessly moving workflows across different platforms.

    • +

  • Can solve the “works on my machine” situation.

    • +

  • For software with many dependencies, in turn with its own dependencies, +containers offer possibly the only way to preserve the +computational experiment for future reproducibility.

    • +

  • A mechanism to “send the computer to the data” when data is too

    • +

  • Installing software into a file instead of into your computer (removing +a file is often easier than uninstalling software if you suddenly regret an +installation)

    • +
+

However, containers may also have some drawbacks:

+
    +

  • Can be used to hide away software installation problems and thereby +discourage good software development practices.

    • +

  • Instead of “works on my machine” problem: “works only in this container” problem?

    • +

  • They can be difficult to modify (this is the focus of an exercise below)

    • +

  • Container images can become large

    • +
+
+

Danger

+

Use only official and trusted images! Not all images can be trusted! There +have been examples of contaminated images so investigate before using images +blindly. Apply same caution as installing software packages from untrusted +package repositories.

+
+
+
+
+

Where can one share or find images?

+ +
+
+
+

Exercises

+
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

(optional) Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash
+

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

In dependencies.md:

+
+

(optional) Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy

+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +

(optional) Dependencies-2: Create a time-capsule for the future

+

Now it is time to create your own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

(optional) Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash

+

This is the planned schedule for the workshop in September 2023 (2 hours and 5 minutes including 10 min break) :

+ +

This was the schedule at workshop in March 2023 (2 hours and 15 minutes including 2x 10 min break):

+ +
+
+

Why we teach this lesson

+

Reproducibility in research is something that publishers, funding agencies, universities, +research leaders and the general public worries about and much is being written about it. +It is also something that researchers care deeply about - this lesson is typically one of the +most popular lessons in the pre-workshop survey.

+

Even though most PhD students, postdocs and researchers (i.e. typical workshop participants) +know about the importance of reproducibility in research, they often lack both a general +overview of what different aspects there are to reproducibility, and the knowledge of +specific tools that can be used for improving reproducibility.

+

Many participants may not adhere to good practices when organizing their projects, +and the “Organizing your projects” episode is meant to encourage participants to +structure their projects better. This may be obvious to some participants but it +doesn’t harm to preach to the choir.

+

Many participants do not share data or code, and in particular they are often +unaware that research output other than published articles can be assigned +digital object identifiers (DOIs). +The “Sharing code and data” is meant to bring awareness about FAIRness and Open Science +and to show how DOIs can be obtained for Git repositories..

+

Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people’s code to run), they +often don’t know or use good practices when it comes to recording dependencies. +Most participants also don’t use isolated environments for different projects and +don’t know why that can be important. +The episode “Recording dependencies” tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager.

+

Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +“Recording environments” introduces the concept of containers, and the optional +episode “Creating and sharing a container image” goes into details.

+

Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of “scientific workflows”, +and that there actually exist tools that help make such workflows reproducible. +The episode “Recording computational steps” introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible.

+
+
+

How to teach this lesson

+
+

How to start

+

Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we’re going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers).

+
+
+

Focus on concepts, and when to use which tool

+

Try to explain better what the different tools are useful for, but don’t go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem.

+
+
+
+

Typical pitfalls

+
+

Indentation in Snakefiles

+
    +

  • the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn’t matter +This works:

    • +
+
rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+
+

but this doesn’t work:

+
rule all:
+    input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+

nor this:

+
rule all:
+input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+
+
+
+

Field reports

+
+

2022 September

+

We used the strategy “absolutely minimal introductions, most time +for exercise”. Overall, it was probably the right thing to do since +there is so little time and so much to cover.

+

There wasn’t enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode.

+

The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn’t really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day.

+

Perhaps we shouldn’t have done the Zenodo example - we could do a +quick demo, but because of limited time, I’m not sure if it conveyed +how cool it was. Maybe we should have simply said it. Alternatively, +we could have not done the Docker demonstration and given more time +for Zenodo.

Reproducible research - Preparing code to be usable by you and others in the future

+

Have you ever spent days trying to repeat the results from few weeks or months +ago? Or you have to do paper revisions, but you just can’t get the results to +match up? It’s unpleasant for both you and science.

+

In this lesson we will explore different methods and tools for better +reproducibility in research software and data. We will demonstrate how version +control, workflows, containers, and package managers can be used to record +reproducible environments and computational steps for our future selves.

+
+

A scary anecdote

+
    +

  • A group of researchers obtain great results and submit their work to a high-profile journal.

    • +

  • Reviewers ask for new figures and additional analysis.

    • +

  • The researchers start working on revisions and generate modified figures, but find inconsistencies with old figures.

    • +

  • The researchers can’t find some of the data they used to generate the original results, and +can’t figure out which parameters they used when running their analyses.

    • +

  • The manuscript is still languishing in the drawer …

    • +
+
+
+
+

Why talking about reproducible research?

+

A 2016 +survey +in Nature revealed that irreproducible experiments are a problem across all +domains of science:

+
+reproduciblity Nature +
+

This study is now few years old but the highlighted problem did not get +smaller.

+
+
+
+

Levels of reproducibility

+

A published article is like the top of a pyramid. It rests on multiple +levels that each contributes to its reproducibility.

Organizing your projects

+
+

Objectives

+
    +

  • Get an overview on how to organize research projects

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching incl. discussions

    • +
+
+

One of the most basic steps to make your work reproducible is to organize your projects well. +Let’s go over some of the basic things which people have found to work (and not to work).

+
+

Directory structure for projects

+
    +

  • Project files in a single folder

    • +

  • Different projects should have separate folders

    • +

  • Use consistent and informative directory structure

    +
      +

    • Avoid spaces in directory and file names – it is uglier for humans but handy for computers.

      • +
    +
    • +

  • If you need to separate public/private, you can put them in public and private Git repos

    +
      +

    • If you need to separate public/secret, use .gitignore or a separate folder that’s not in Git

      • +
    +
    • +

  • Add a README file to describe the project and instructions on reproducing the results

    • +

  • If a software is reused in several projects it can make sense to put them in own repo

    • +
+

A project directory can look something like this:

+
project_name/
+├── README.md             # overview of the project
+├── data/                 # data files used in the project
+│   ├── README.md         # describes where data came from
+│   └── sub-folder/       # may contain subdirectories
+├── processed_data/       # intermediate files from the analysis
+├── manuscript/           # manuscript describing the results
+├── results/              # results of the analysis (data, tables, figures)
+├── src/                  # contains all code in the project
+│   ├── LICENSE           # license for your code
+│   ├── requirements.txt  # software requirements and dependencies
+│   └── ...
+└── doc/                  # documentation for your project
+    ├── index.rst
+    └── ...
+
+
+
+
+
+

Tracking source code, data, and results

+
    +

  • All code is version controlled and goes in the src/ or source/ directory

    • +

  • Include appropriate LICENSE file and information on software requirements

    • +

  • You can also version control data files or input files under data/

    • +

  • If data files are too large (or sensitive) to track, untrack them using .gitignore

    • +

  • Intermediate files from the analysis are kept in processed_data/

    • +

  • Consider using Git tags to mark specific versions of results (version +submitted to a journal, dissertation version, poster version, etc.):

    +
    $ git tag -a thesis-submitted -m "this is the submitted version of my thesis"
+
    +
    +
    • +
+ +
+
+
+

Reproducible publications

+
    +

  • Git can be used to collaborate on manuscripts written in, e.g., LaTeX and other text-based formats but other tools exist:

    +
      +

    • Overleaf: an online, collaborative LaTeX editor (has Git integration)

      • +

    • Authorea: collaborative platform for preprints (apparently also has Git integration)

      • +

    • HackMD: an online collaborative Markdown editor (has Git integration)

      • +

    • Manuscripts.io: a collaborative authoring tool that support scientific content and reproducibility.

      • +

    • Google Docs can be a good alternative

      • +
    +
    • +

  • Many tools exist to assist in making scholarly output reproducible:

    +
      +

    • rrtools: instructions, templates, and functions for writing a reproducible article or report with R.

      • +

    • Jupyter Notebooks: web-based computational environment for creating code and text based notebooks that can be used as +supplementary material for articles.

      • +

    • Binder: makes a repository with Jupyter notebooks available in an executable environment (discussed later in the Jupyter lesson).

      • +

    • “Research compendia”: a set of good practices for +reproducible data analysis in R, but much is transferable to other languages.

Recording computational steps

+
+

Questions

+
    +

  • You have some steps that need to be run to do your work. How do you +actually run them? Does it rely on your own memory and work, or is it +reproducible? How do you communicate the steps for future you and others?

    • +

  • How can we create a reproducible workflow?

    • +

  • When to use scientific workflow management systems.

    • +
+

Several steps from input data to result

+

The following material is partly derived from a HPC Carpentry lesson.

+

In this episode, we will use an example +project which finds most frequent +words in books and plots the result from those statistics. In this example we +wish to:

+
    +

  1. Analyze word frequencies using statistics/count.py +for 4 books +(they are all in the data directory).

    2. +

  2. Plot a histogram using plot/plot.py.

    3. +
+
+From book to word counts to plot +
+

Example (for one book only):

+
$ python statistics/count.py data/isles.txt > statistics/isles.data
+$ python plot/plot.py --data-file statistics/isles.data --plot-file plot/isles.png
+
+
+
+

Discussion

+

We have two steps and 4 books. But imagine having 4 steps and processing 500 books. +Can you relate? Are you using similar setups in your research? How do you record them?

+
+
+

Kitchen analogy

+
+Busy kitchen +
+

Now we have many similar meals to prepare and possibly many chefs +present (cores) and workflow tools can help us to plan and document the steps +and run them efficiently. [Midjourney, CC-BY-NC 4.0]

+

Exercise

+
+

Exercise preparation

+

The exercise (below) and pre-exercise discussion uses a simple +word-count repository +(https://github.com/coderefinery/word-count). We should clone the +repository already to prepare to work on it.

+

You could do the exercise either on your own computer, or the Binder +cloud service:

+

On your own computer:

+
    +

  • Activate the coderefinery conda environment with conda activate coderefinery.

    • +

  • Clone the word-count repository:

    +
    $ git clone https://github.com/coderefinery/word-count.git
+
    +
    +
    • +
+

On Binder: +We can also use the cloud service Binder to make sure +we all have the same computing environment. This is interesting from a +reproducible research point of view and it’s explained further in the Jupyter +lesson how this is even +possible.

+
    +

  • Go to https://github.com/coderefinery/word-count and click on the “launch binder” badge in the README.

    • +

  • Once it get started, you can open a new Terminal from the new menu (top right) and select Terminal.

    • +
+
+
+

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

    • +
+ +
+
+

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

    10. +
+ +
+
+
+

Why Snakemake?

+
    +

  • Gentle learning curve.

    • +

  • Free, open-source, and installs easily via conda or pip.

    • +

  • Cross-platform (Windows, MacOS, Linux) and compatible with all HPC schedulers: +same workflow works without modification and scales appropriately whether on a laptop or cluster.

    • +

  • Heavily used in bioinformatics, but is completely general.

    • +

  • Is is possible to define isolated software environments per rule, see here.

    • +

  • Also possible to run workflows in Docker or Apptainer containers.

    • +

  • Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up.

    • +

  • If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel.

    • +

  • Nice functionality for archiving the workflow, see: the official documentation

    • +
+
+
+

Similar tools

+ +
+
+

Visualizing the workflow

+

We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the --dag option, which will output the DAG in dot language.

+

Note: This requires the Graphviz software, +which can be installed by conda install graphviz. It’s not necessary to +run this step yourself.

+
$ snakemake -j 1 --dag | dot -Tpng > dag.png
+
+
+

Rules that have yet to be completed are indicated with solid outlines, while already completed rules are indicated with dashed outlines.

This may be obvious to some participants but it +doesn't harm to preach to the choir. + +Many participants do not share data or code, and in particular they are often +unaware that research output other than published articles can be assigned +digital object identifiers (DOIs). +The "Sharing code and data" is meant to bring awareness about FAIRness and Open Science +and to show how DOIs can be obtained for Git repositories.. + +Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people's code to run), they +often don't know or use good practices when it comes to recording dependencies. +Most participants also don't use isolated environments for different projects and +don't know why that can be important. +The episode "Recording dependencies" tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager. + +Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +"Recording environments" introduces the concept of containers, and the optional +episode "Creating and sharing a container image" goes into details. + +Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of "scientific workflows", +and that there actually exist tools that help make such workflows reproducible. +The episode "Recording computational steps" introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible. + + +## How to teach this lesson + +### How to start + +Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we're going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers). + + +### Focus on concepts, and when to use which tool + +Try to explain better what the different tools are useful for, but don't go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem. + + +## Typical pitfalls + +### Indentation in Snakefiles + +- the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn't matter +This works: +```python +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` +but this doesn't work: +```python +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` +nor this: +```python +rule all: +input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` + + +## Field reports + +### 2022 September + +We used the strategy "absolutely minimal introductions, most time +for exercise". Overall, it was probably the right thing to do since +there is so little time and so much to cover. + +There wasn't enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode. + +The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn't really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day. + +Perhaps we shouldn't have done the Zenodo example - we could do a +quick demo, but because of limited time, I'm not sure if it conveyed +how cool it was. Maybe we should have simply said it. Alternatively, +we could have not done the Docker demonstration and given more time +for Zenodo. diff --git a/branch/links/_sources/index.rst.txt b/branch/links/_sources/index.rst.txt new file mode 100644 index 0000000..ab74220 --- /dev/null +++ b/branch/links/_sources/index.rst.txt @@ -0,0 +1,58 @@ +.. _index: + +Reproducible research - Preparing code to be usable by you and others in the future +=================================================================================== + +Have you ever spent days **trying to repeat the results from few weeks or months +ago**?

Tools and what problems they try to solve

+

Conda, Anaconda, pip, virtualenv, Pipenv, pyenv, Poetry, requirements.txt, +environment.yml, renv, …, these tools try to solve the following problems:

+
    +

  • Defining a specific set of dependencies, possibly with well defined versions

    • +

  • Installing those dependencies mostly automatically

    • +

  • Recording the versions for all dependencies

    • +

  • Isolate environments

    +
      +

    • On your computer for projects so they can use different software

      • +

    • Isolate environments on computers with many users (and allow self-installations)

      • +
    +
    • +

  • Using different Python/R versions per project

    • +

  • Provide tools and services to share packages

    • +
+

Isolated environments are also useful because they help you make sure +that you know your dependencies!

+

If things go wrong, you can delete and re-create - much better +than debugging. The more often you re-create your environment, the +more reproducible it is.

Exercises

+
+

Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click
+  - python
+  - pip
+  - pip:
+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4
+  - sympy=1.4
+  - click=7.0
+  - python=3.8
+  - pip
+  - pip:

+    - git+https://github.com/anotheruser/anotherproject.git@sometag
+
    +
    +

    E: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4

Dependencies-2: Create a time-capsule for the future

+

Now it is time to create your own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+
+
+

What is a container?

+

Imagine if you didn’t have to install things yourself, but instead you could +get a computer with the exact software for a task pre-installed? Containers +effectively do that, with various advantages and disadvantages. They are +like an entire operating system with software installed, all in one file,

+He said, then we will ship your machine. And that's how Docker was born. +

Kitchen analogy

+
    +

  • Our codes/scripts <-> cooking recipes

    • +

  • Container definition files <-> like a blueprint to build a kitchen with all +utensils in which the recipe can be prepared.

    • +

  • Container images <-> example kitchens

    • +

  • Containers <-> identical factory-built mobile food truck kitchens

    • +
+

Just for fun: which operating systems do the following example kitchens represent?

From definition files to container images to containers

+
    +

  • Containers can be built to bundle all the necessary ingredients (data, code, environment, operating system).

    • +

  • A container image is like a piece of paper with all the operating system on it. When you run it, +a transparent sheet is placed on top to form a container. The container runs and writes only on +that transparent sheet (and what other mounts have been layered on top). When you are done, +transparency is thrown away. It can be repeated as often as you want, and base is always the same.

    • +

  • Definition files (e.g. Dockerfile or Singularity definition file) are text +files that contain a series of instructions to build container images.

    • +
+

Here is an example of a Singularity definition file (reference):

+
Bootstrap: docker
+From: ubuntu:20.04
+
+%post
+    apt-get -y update
+    apt-get -y install cowsay lolcat
+
+%environment
+    export LC_ALL=C
+    export PATH=/usr/games:$PATH
+
+%runscript
+    date | cowsay | lolcat
+
+
+

Popular container implementations:

+ +

They are to some extent interoperable:

+
    +

  • podman is very close to Docker

    • +

  • Docker images can be converted to Singularity/Apptainer images

    • +

  • Singularity Python can convert Dockerfiles to Singularity definition files

    • +
+
+
+
+

Pros and cons of containers

+

Containers are popular for a reason - they solve a number of +important problems:

+
    +

  • Allow for seamlessly moving workflows across different platforms.

    • +

  • Can solve the “works on my machine” situation.

    • +

  • For software with many dependencies, in turn with its own dependencies, +containers offer possibly the only way to preserve the +computational experiment for future reproducibility.

    • +

  • A mechanism to “send the computer to the data” when data is too

    • +

  • Installing software into a file instead of into your computer (removing +a file is often easier than uninstalling software if you suddenly regret an +installation)

    • +
+

However, containers may also have some drawbacks:

+
    +

  • Can be used to hide away software installation problems and thereby +discourage good software development practices.

    • +

  • Instead of “works on my machine” problem: “works only in this container” problem?

    • +

  • They can be difficult to modify (this is the focus of an exercise below)

    • +

  • Container images can become large

    • +
+
+

Danger

+

Use only official and trusted images! Not all images can be trusted! There +have been examples of contaminated images so investigate before using images +blindly. Apply same caution as installing software packages from untrusted +package repositories.

+
+
+
+
+

Where can one share or find images?

+ +
+
+
+

Exercises

+
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash
+
    +

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

+

Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project

Dependencies-2: Create a time-capsule for the future

+

Now it is time to create your own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+
+
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash

+

This is the planned schedule for the workshop in September 2023 (2 hours and 5 minutes including 10 min break) :

+ +

This was the schedule at workshop in March 2023 (2 hours and 15 minutes including 2x 10 min break):

+ +
+
+

Why we teach this lesson

+

Reproducibility in research is something that publishers, funding agencies, universities, +research leaders and the general public worries about and much is being written about it. +It is also something that researchers care deeply about - this lesson is typically one of the +most popular lessons in the pre-workshop survey.

+

Even though most PhD students, postdocs and researchers (i.e. typical workshop participants) +know about the importance of reproducibility in research, they often lack both a general +overview of what different aspects there are to reproducibility, and the knowledge of +specific tools that can be used for improving reproducibility.

+

Many participants may not adhere to good practices when organizing their projects, +and the “Organizing your projects” episode is meant to encourage participants to +structure their projects better. This may be obvious to some participants but it +doesn’t harm to preach to the choir.

+

Many participants do not share data or code, and in particular they are often +unaware that research output other than published articles can be assigned +digital object identifiers (DOIs). +The “Sharing code and data” is meant to bring awareness about FAIRness and Open Science +and to show how DOIs can be obtained for Git repositories..

+

Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people’s code to run), they +often don’t know or use good practices when it comes to recording dependencies. +Most participants also don’t use isolated environments for different projects and +don’t know why that can be important. +The episode “Recording dependencies” tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager.

+

Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +“Recording environments” introduces the concept of containers, and the optional +episode “Creating and sharing a container image” goes into details.

+

Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of “scientific workflows”, +and that there actually exist tools that help make such workflows reproducible. +The episode “Recording computational steps” introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible.

+
+
+

How to teach this lesson

+
+

How to start

+

Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we’re going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers).

+
+
+

Focus on concepts, and when to use which tool

+

Try to explain better what the different tools are useful for, but don’t go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem.

+
+
+
+

Typical pitfalls

+
+

Indentation in Snakefiles

+
    +

  • the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn’t matter +This works:

    • +
+
rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+
+

but this doesn’t work:

+
rule all:
+    input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+

nor this:

+
rule all:
+input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+
+
+
+

Field reports

+
+

2022 September

+

We used the strategy “absolutely minimal introductions, most time +for exercise”. Overall, it was probably the right thing to do since +there is so little time and so much to cover.

+

There wasn’t enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode.

+

The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn’t really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day.

+

Perhaps we shouldn’t have done the Zenodo example - we could do a +quick demo, but because of limited time, I’m not sure if it conveyed +how cool it was. Maybe we should have simply said it. Alternatively, +we could have not done the Docker demonstration and given more time +for Zenodo.

Reproducible research - Preparing code to be usable by you and others in the future

+

Have you ever spent days trying to repeat the results from few weeks or months +ago? Or you have to do paper revisions, but you just can’t get the results to +match up? It’s unpleasant for both you and science.

+

In this lesson we will explore different methods and tools for better +reproducibility in research software and data. We will demonstrate how version +control, workflows, containers, and package managers can be used to record +reproducible environments and computational steps for our future selves.

+
+

A scary anecdote

+
    +

  • A group of researchers obtain great results and submit their work to a high-profile journal.

    • +

  • Reviewers ask for new figures and additional analysis.

    • +

  • The researchers start working on revisions and generate modified figures, but find inconsistencies with old figures.

    • +

  • The researchers can’t find some of the data they used to generate the original results, and +can’t figure out which parameters they used when running their analyses.

    • +

  • The manuscript is still languishing in the drawer …

    • +
+
+
+
+

Why talking about reproducible research?

+

A 2016 +survey +in Nature revealed that irreproducible experiments are a problem across all +domains of science:

+
+reproduciblity Nature +
+

This study is now few years old but the highlighted problem did not get +smaller.

+
+
+
+

Levels of reproducibility

+

A published article is like the top of a pyramid. It rests on multiple +levels that each contributes to its reproducibility.

Organizing your projects

+
+

Objectives

+
    +

  • Get an overview on how to organize research projects

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching incl. discussions

    • +
+
+

One of the most basic steps to make your work reproducible is to organize your projects well. +Let’s go over some of the basic things which people have found to work (and not to work).

+
+

Directory structure for projects

+
    +

  • Project files in a single folder

    • +

  • Different projects should have separate folders

    • +

  • Use consistent and informative directory structure

    +
      +

    • Avoid spaces in directory and file names – it is uglier for humans but handy for computers.

      • +
    +
    • +

  • If you need to separate public/private, you can put them in public and private Git repos

    +
      +

    • If you need to separate public/secret, use .gitignore or a separate folder that’s not in Git

      • +
    +
    • +

  • Add a README file to describe the project and instructions on reproducing the results

    • +

  • If a software is reused in several projects it can make sense to put them in own repo

    • +
+

A project directory can look something like this:

+
project_name/
+├── README.md             # overview of the project
+├── data/                 # data files used in the project
+│   ├── README.md         # describes where data came from
+│   └── sub-folder/       # may contain subdirectories
+├── processed_data/       # intermediate files from the analysis
+├── manuscript/           # manuscript describing the results
+├── results/              # results of the analysis (data, tables, figures)
+├── src/                  # contains all code in the project
+│   ├── LICENSE           # license for your code
+│   ├── requirements.txt  # software requirements and dependencies
+│   └── ...
+└── doc/                  # documentation for your project
+    ├── index.rst
+    └── ...
+
+
+
+
+
+

Tracking source code, data, and results

+
    +

  • All code is version controlled and goes in the src/ or source/ directory

    • +

  • Include appropriate LICENSE file and information on software requirements

    • +

  • You can also version control data files or input files under data/

    • +

  • If data files are too large (or sensitive) to track, untrack them using .gitignore

    • +

  • Intermediate files from the analysis are kept in processed_data/

    • +

  • Consider using Git tags to mark specific versions of results (version +submitted to a journal, dissertation version, poster version, etc.):

    +
    $ git tag -a thesis-submitted -m "this is the submitted version of my thesis"
+
    +
    +
    • +
+ +
+
+
+

Reproducible publications

+
    +

  • Git can be used to collaborate on manuscripts written in, e.g., LaTeX and other text-based formats but other tools exist:

    +
      +

    • Overleaf: an online, collaborative LaTeX editor (has Git integration)

      • +

    • Authorea: collaborative platform for preprints (apparently also has Git integration)

      • +

    • HackMD: an online collaborative Markdown editor (has Git integration)

      • +

    • Manuscripts.io: a collaborative authoring tool that support scientific content and reproducibility.

      • +

    • Google Docs can be a good alternative

      • +
    +
    • +

  • Many tools exist to assist in making scholarly output reproducible:

    +
      +

    • rrtools: instructions, templates, and functions for writing a reproducible article or report with R.

      • +

    • Jupyter Notebooks: web-based computational environment for creating code and text based notebooks that can be used as +supplementary material for articles.

      • +

    • Binder: makes a repository with Jupyter notebooks available in an executable environment (discussed later in the Jupyter lesson).

      • +

    • “Research compendia”: a set of good practices for +reproducible data analysis in R, but much is transferable to other languages.

Recording computational steps

+
+

Questions

+
    +

  • You have some steps that need to be run to do your work. How do you +actually run them? Does it rely on your own memory and work, or is it +reproducible? How do you communicate the steps for future you and others?

    • +

  • How can we create a reproducible workflow?

    • +

  • When to use scientific workflow management systems.

    • +
+
+
+

Several steps from input data to result

+

The following material is partly derived from a HPC Carpentry lesson.

+

In this episode, we will use an example +project which finds most frequent +words in books and plots the result from those statistics. In this example we +wish to:

+
    +

  1. Analyze word frequencies using statistics/count.py +for 4 books +(they are all in the data directory).

    2. +

  2. Plot a histogram using plot/plot.py.

    3. +
+
+From book to word counts to plot +
+

Example (for one book only):

+
$ python statistics/count.py data/isles.txt > statistics/isles.data
+$ python plot/plot.py --data-file statistics/isles.data --plot-file plot/isles.png
+
+
+
+

Discussion

+

We have two steps and 4 books. But imagine having 4 steps and processing 500 books. +Can you relate? Are you using similar setups in your research? How do you record them?

+
+
+

Kitchen analogy

+
+Busy kitchen +
+

Now we have many similar meals to prepare and possibly many chefs +present (cores) and workflow tools can help us to plan and document the steps +and run them efficiently. [Midjourney, CC-BY-NC 4.0]

+
+

Exercise

+
+

Exercise preparation

+

The exercise (below) and pre-exercise discussion uses a simple +word-count repository +(https://github.com/coderefinery/word-count). We should clone the +repository already to prepare to work on it.

+

You could do the exercise either on your own computer, or the Binder +cloud service:

+

On your own computer:

+
    +

  • Activate the coderefinery conda environment with conda activate coderefinery.

    • +

  • Clone the word-count repository:

    +
    $ git clone https://github.com/coderefinery/word-count.git
+
    +
    +
    • +
+

On Binder: +We can also use the cloud service Binder to make sure +we all have the same computing environment. This is interesting from a +reproducible research point of view and it’s explained further in the Jupyter +lesson how this is even +possible.

+
    +

  • Go to https://github.com/coderefinery/word-count and click on the “launch binder” badge in the README.

    • +

  • Once it get started, you can open a new Terminal from the new menu (top right) and select Terminal.

    • +
+
+
+

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

    • +
+ +
+
+

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

    10. +
+ +
+
+
+

Why Snakemake?

+
    +

  • Gentle learning curve.

    • +

  • Free, open-source, and installs easily via conda or pip.

    • +

  • Cross-platform (Windows, MacOS, Linux) and compatible with all HPC schedulers: +same workflow works without modification and scales appropriately whether on a laptop or cluster.

    • +

  • Heavily used in bioinformatics, but is completely general.

    • +

  • Is is possible to define isolated software environments per rule, see here.

    • +

  • Also possible to run workflows in Docker or Apptainer containers.

    • +

  • Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up.

    • +

  • If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel.

    • +

  • Nice functionality for archiving the workflow, see: the official documentation

    • +
+
+
+

Similar tools

+ +
+
+

Visualizing the workflow

+

We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the --dag option, which will output the DAG in dot language.

+

Note: This requires the Graphviz software, +which can be installed by conda install graphviz. It’s not necessary to +run this step yourself.

+
$ snakemake -j 1 --dag | dot -Tpng > dag.png
+
+
+

Rules that have yet to be completed are indicated with solid outlines, while already completed rules are indicated with dashed outlines.

This may be obvious to some participants but it +doesn't harm to preach to the choir. + +Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people's code to run), they +often don't know or use good practices when it comes to recording dependencies. +Most participants also don't use isolated environments for different projects and +don't know why that can be important. +The episode "Recording dependencies" tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager. + +Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +"Recording environments" introduces the concept of containers, and the optional +episode "Creating and sharing a container image" goes into details. + +Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of "scientific workflows", +and that there actually exist tools that help make such workflows reproducible. +The episode "Recording computational steps" introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible. + + +## How to teach this lesson + +### How to start + +Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this.

In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem. + + +## Typical pitfalls + +### Indentation in Snakefiles + +- the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn't matter +This works: +```python +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` +but this doesn't work: +```python +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` +nor this: +```python +rule all: +input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` + + +## Field reports + +### 2022 September + +We used the strategy "absolutely minimal introductions, most time +for exercise". Overall, it was probably the right thing to do since +there is so little time and so much to cover. + +There wasn't enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode. + +The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn't really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day. + diff --git a/branch/main/_sources/index.rst.txt b/branch/main/_sources/index.rst.txt new file mode 100644 index 0000000..1af87bd --- /dev/null +++ b/branch/main/_sources/index.rst.txt @@ -0,0 +1,60 @@ +.. _index: + +Reproducible research - Preparing code to be usable by you and others in the future +=================================================================================== + +Have you ever spent days **trying to repeat the results from few weeks or months +ago**?

Recording dependencies

+
+

Questions

+
    +

  • How can we communicate different versions of software dependencies?

    • +
+

Our codes often depend on other codes that in turn depend on other codes …

+
    +

  • Reproducibility: We can version-control our code with Git but how should we version-control dependencies? +How can we capture and communicate dependencies?

    • +

  • Dependency hell: Different codes on the same environment can have conflicting dependencies.

Tools and what problems they try to solve

+

Conda, Anaconda, pip, virtualenv, Pipenv, pyenv, Poetry, requirements.txt, +environment.yml, renv, …, these tools try to solve the following problems:

+
    +

  • Defining a specific set of dependencies, possibly with well defined versions

    • +

  • Installing those dependencies mostly automatically

    • +

  • Recording the versions for all dependencies

    • +

  • Isolate environments

    +
      +

    • On your computer for projects so they can use different software

      • +

    • Isolate environments on computers with many users (and allow self-installations)

      • +
    +
    • +

  • Using different Python/R versions per project

    • +

  • Provide tools and services to share packages

    • +
+

Isolated environments are also useful because they help you make sure +that you know your dependencies!

+

If things go wrong, you can delete and re-create - much better +than debugging. The more often you re-create your environment, the +more reproducible it is.

Exercises

+
+

(optional) Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+

Answer in the collaborative document:

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click
+  - python
+  - pip
+  - pip:
+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4

+    - git+https://github.com/anotheruser/anotherproject.git@sometag
+
    +
    +

    E: +You find a environment.yml file with:

    +
    name: student-project
+channels:

(optional) Dependencies-2: Create a time-capsule for the future

+

Now it is time to create your own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+
+
+

What is a container?

+

Imagine if you didn’t have to install things yourself, but instead you could +get a computer with the exact software for a task pre-installed? Containers +effectively do that, with various advantages and disadvantages. They are +like an entire operating system with software installed, all in one file,

+
+He said, then we will ship your machine. And that's how Docker was born. +

Kitchen analogy

+
    +

  • Our codes/scripts <-> cooking recipes

    • +

  • Container definition files <-> like a blueprint to build a kitchen with all +utensils in which the recipe can be prepared.

    • +

  • Container images <-> example kitchens

    • +

  • Containers <-> identical factory-built mobile food truck kitchens

    • +
+

Just for fun: which operating systems do the following example kitchens represent?

+

From definition files to container images to containers

+
    +

  • Containers can be built to bundle all the necessary ingredients (data, code, environment, operating system).

    • +

  • A container image is like a piece of paper with all the operating system on it. When you run it, +a transparent sheet is placed on top to form a container. The container runs and writes only on +that transparent sheet (and what other mounts have been layered on top). When you are done, +transparency is thrown away. It can be repeated as often as you want, and base is always the same.

    • +

  • Definition files (e.g. Dockerfile or Singularity definition file) are text +files that contain a series of instructions to build container images.

    • +
+
+
+

You may have use for containers in different ways

+
    +

  • Installing a certain software is tricky, or not supported for your operating system? -> See if an image is available and run the software from a container instead!

    • +

  • You want to make sure your colleagues are using the same environment for running your code? -> Provide them an image of your container!

    +
      +

    • If this does not work, because they are using a different architecture than you do? -> Provide a definition file for them to build the image suitable to their computers. This does not create the exact environment as you have, but in most cases similar enough.

      • +
    +
    • +
+
+
+

The container recipe

+

Here is an example of a Singularity definition file (reference):

+
Bootstrap: docker
+From: ubuntu:20.04
+
+%post
+    apt-get -y update
+    apt-get -y install cowsay lolcat
+
+%environment
+    export LC_ALL=C
+    export PATH=/usr/games:$PATH
+
+%runscript
+    date | cowsay | lolcat
+
+
+

Popular container implementations:

+ +

They are to some extent interoperable:

+
    +

  • podman is very close to Docker

    • +

  • Docker images can be converted to Singularity/Apptainer images

    • +

  • Singularity Python can convert Dockerfiles to Singularity definition files

    • +
+
+
+
+

Pros and cons of containers

+

Containers are popular for a reason - they solve a number of +important problems:

+
    +

  • Allow for seamlessly moving workflows across different platforms.

    • +

  • Can solve the “works on my machine” situation.

    • +

  • For software with many dependencies, in turn with its own dependencies, +containers offer possibly the only way to preserve the +computational experiment for future reproducibility.

    • +

  • A mechanism to “send the computer to the data” when data is too

    • +

  • Installing software into a file instead of into your computer (removing +a file is often easier than uninstalling software if you suddenly regret an +installation)

    • +
+

However, containers may also have some drawbacks:

+
    +

  • Can be used to hide away software installation problems and thereby +discourage good software development practices.

    • +

  • Instead of “works on my machine” problem: “works only in this container” problem?

    • +

  • They can be difficult to modify (this is the focus of an exercise below)

    • +

  • Container images can become large

    • +
+
+

Danger

+

Use only official and trusted images! Not all images can be trusted! There +have been examples of contaminated images so investigate before using images +blindly. Apply same caution as installing software packages from untrusted +package repositories.

+
+
+
+
+

Where can one share or find images?

+ +
+
+
+

Exercises

+
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

(optional) Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash
+
    +

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

(optional) Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+

Answer in the collaborative document:

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click

+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4

+    - git+https://github.com/anotheruser/anotherproject.git@sometag
+
    +
    +

    E: +You find a environment.yml file with:

    +
    name: student-project

+

Why we teach this lesson

+

Reproducibility in research is something that publishers, funding agencies, universities, +research leaders and the general public worries about and much is being written about it. +It is also something that researchers care deeply about - this lesson is typically one of the +most popular lessons in the pre-workshop survey.

+

Even though most PhD students, postdocs and researchers (i.e. typical workshop participants) +know about the importance of reproducibility in research, they often lack both a general +overview of what different aspects there are to reproducibility, and the knowledge of +specific tools that can be used for improving reproducibility.

+

Many participants may not adhere to good practices when organizing their projects, +and the “Organizing your projects” episode is meant to encourage participants to +structure their projects better. This may be obvious to some participants but it +doesn’t harm to preach to the choir.

+

Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people’s code to run), they +often don’t know or use good practices when it comes to recording dependencies. +Most participants also don’t use isolated environments for different projects and +don’t know why that can be important. +The episode “Recording dependencies” tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager.

+

Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +“Recording environments” introduces the concept of containers, and the optional +episode “Creating and sharing a container image” goes into details.

+

Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of “scientific workflows”, +and that there actually exist tools that help make such workflows reproducible. +The episode “Recording computational steps” introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible.

+

Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we’re going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers).

+
+
+

Focus on concepts, and when to use which tool

+

Try to explain better what the different tools are useful for, but don’t go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem.

+
+
+
+

Typical pitfalls

+
+

Indentation in Snakefiles

+
    +

  • the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn’t matter +This works:

    • +
+
rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+
+

but this doesn’t work:

+
rule all:
+    input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+

nor this:

+
rule all:
+input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+
+
+
+

Field reports

+
+

2022 September

+

We used the strategy “absolutely minimal introductions, most time +for exercise”. Overall, it was probably the right thing to do since +there is so little time and so much to cover.

+

There wasn’t enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode.

+

The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn’t really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day.

Reproducible research - Preparing code to be usable by you and others in the future

+

Have you ever spent days trying to repeat the results from few weeks or months +ago? Or you have to do paper revisions, but you just can’t get the results to +match up? It’s unpleasant for both you and science.

+

In this lesson we will explore different methods and tools for better +reproducibility in research software and data. We will demonstrate how version +control, workflows, containers, and package managers can be used to record +reproducible environments and computational steps for our future selves.

+
+

A scary anecdote

+
    +

  • A group of researchers obtain great results and submit their work to a high-profile journal.

    • +

  • Reviewers ask for new figures and additional analysis.

    • +

  • The researchers start working on revisions and generate modified figures, but find inconsistencies with old figures.

    • +

  • The researchers can’t find some of the data they used to generate the original results, and +can’t figure out which parameters they used when running their analyses.

    • +

  • The manuscript is still languishing in the drawer …

    • +
+
+
+
+

Why talking about reproducible research?

+

A 2016 +survey +in Nature revealed that irreproducible experiments are a problem across all +domains of science:

+
+reproduciblity Nature +
+

This study is now few years old but the highlighted problem did not get +smaller.

+
+
+
+

Levels of reproducibility

+

A published article is like the top of a pyramid. It rests on multiple +levels that each contributes to its reproducibility.

+

This also means that you can think about it from the beginning of your research life cycle!

Organizing your projects

+
+

Objectives

+
    +

  • Get an overview on how to organize research projects

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching incl. discussions

    • +
+
+

One of the most basic steps to make your work reproducible is to organize your projects well. +Let’s go over some of the basic things which people have found to work (and not to work).

+
+

Directory structure for projects

+
    +

  • Project files in a single folder

    • +

  • Different projects should have separate folders

    • +

  • Use consistent and informative directory structure

    +
      +

    • Avoid spaces in directory and file names – it is uglier for humans but handy for computers.

      • +
    +
    • +

  • If you need to separate public/private, you can put them in public and private Git repos

    +
      +

    • If you need to separate public/secret, use .gitignore or a separate folder that’s not in Git

      • +
    +
    • +

  • Add a README file to describe the project and instructions on reproducing the results

    • +

  • If a software is reused in several projects it can make sense to put them in own repo

    • +
+

A project directory can look something like this:

+
project_name/
+├── README.md             # overview of the project
+├── data/                 # data files used in the project
+│   ├── README.md         # describes where data came from
+│   └── sub-folder/       # may contain subdirectories
+├── processed_data/       # intermediate files from the analysis
+├── manuscript/           # manuscript describing the results
+├── results/              # results of the analysis (data, tables, figures)
+├── src/                  # contains all code in the project
+│   ├── LICENSE           # license for your code
+│   ├── requirements.txt  # software requirements and dependencies
+│   └── ...
+└── doc/                  # documentation for your project
+    ├── index.rst
+    └── ...
+
+
+
+
+
+

Tracking source code, data, and results

+
    +

  • All code is version controlled and goes in the src/ or source/ directory

    • +

  • Include appropriate LICENSE file and information on software requirements

    • +

  • You can also version control data files or input files under data/

    • +

  • If data files are too large (or sensitive) to track, untrack them using .gitignore

    • +

  • Intermediate files from the analysis are kept in processed_data/

    • +

  • Consider using Git tags to mark specific versions of results (version +submitted to a journal, dissertation version, poster version, etc.):

    +
    $ git tag -a thesis-submitted -m "this is the submitted version of my thesis"
+
    +
    +
    • +
+ +
+
+
+

Reproducible publications

+
    +

  • Git can be used to collaborate on manuscripts written in, e.g., LaTeX and other text-based formats but other tools exist:

    +
      +

    • Overleaf: an online, collaborative LaTeX editor (has Git integration)

      • +

    • Authorea: collaborative platform for preprints (apparently also has Git integration)

      • +

    • HackMD: an online collaborative Markdown editor (has Git integration)

      • +

    • Manuscripts.io: a collaborative authoring tool that support scientific content and reproducibility.

      • +

    • Google Docs can be a good alternative

      • +
    +
    • +

  • Many tools exist to assist in making scholarly output reproducible:

    +
      +

    • rrtools: instructions, templates, and functions for writing a reproducible article or report with R.

      • +

    • Jupyter Notebooks: web-based computational environment for creating code and text based notebooks that can be used as, see also our Jupyter lesson later in this workshop. +supplementary material for articles.

      • +

    • Binder: makes a repository with Jupyter notebooks available in an executable environment (discussed later in the Jupyter lesson).

      • +

    • “Research compendia”: a set of good practices for +reproducible data analysis in R, but much is transferable to other languages.

+
- Are you using version control for academic papers?
+  - ...
+  - ...
+  - (share your experience)
+
+- How do you handle collaborative issues e.g. conflicting changes?
+  - ...
+  - ...
+  - (share your experience)
+
+
+
+

Please write or discuss your ideas before opening solution!

+
+ +

+

Keypoints

+
    +

  • An organized project directory structure helps with reproducibility.

    • +

  • Reproducibility makes work easier for the next person working on the project - and that might be you in a few years!

Reproducible research - Preparing code to be usable by you and others in the future

+

Have you ever spent days trying to repeat the results from few weeks or months +ago? Or you have to do paper revisions, but you just can’t get the results to +match up? It’s unpleasant for both you and science.

+

In this lesson we will explore different methods and tools for better +reproducibility in research software and data. We will demonstrate how version +control, workflows, containers, and package managers can be used to record +reproducible environments and computational steps for our future selves.

+
+

+
By the end of this lesson, learners should:
    +

  • be able to apply well organized directory structure for their project

    • +

  • remember the FAIR principles

    • +

  • understand that code can have dependencies, and know how to document them

    • +

  • if a computational studies contains several steps, be able to document them

    • +

  • know about use cases for containers

    • +

  • knowing the pros and cons of manual documentation vs. scripted automation vs. workflow management

    • +
+
+
+

A scary anecdote

+
    +

  • A group of researchers obtain great results and submit their work to a high-profile journal.

    • +

  • Reviewers ask for new figures and additional analysis.

    • +

  • The researchers start working on revisions and generate modified figures, but find inconsistencies with old figures.

    • +

  • The researchers can’t find some of the data they used to generate the original results, and +can’t figure out which parameters they used when running their analyses.

    • +

  • The manuscript is still languishing in the drawer …

    • +
+
+
+
+

Why talking about reproducible research?

+

A 2016 +survey +in Nature revealed that irreproducible experiments are a problem across all +domains of science:

+
+reproduciblity Nature +
+

This study is now few years old but the highlighted problem did not get +smaller.

+
+
+
+

Levels of reproducibility

+

A published article is like the top of a pyramid. It rests on multiple +levels that each contributes to its reproducibility.

+
+Reproducibility pyramid +
+

+

This also means that you can think about it from the beginning of your research life cycle!

+
+
+

Discuss in collaborative document or with your team members

+
- What are your experiences re-running or adjusting a script or a figure you
+  created few months ago?
+  - ...
+  - ...
+  - (share your experience)
+
+- Have you continued working from a previous student's

Organizing your projects

+
+

Objectives

+
    +

  • Get an overview on how to organize research projects

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching incl. discussions

    • +
+
+

One of the most basic steps to make your work reproducible is to organize your projects well. +Let’s go over some of the basic things which people have found to work (and not to work).

+
+

Directory structure for projects

+
    +

  • Project files in a single folder

    • +

  • Different projects should have separate folders

    • +

  • Use consistent and informative directory structure

    +
      +

    • Avoid spaces in directory and file names – it is uglier for humans but handy for computers.

      • +
    +
    • +

  • If you need to separate public/private, you can put them in public and private Git repos

    +
      +

    • If you need to separate public/secret, use .gitignore or a separate folder that’s not in Git

      • +
    +
    • +

  • Add a README file to describe the project and instructions on reproducing the results

    • +

  • If a software is reused in several projects it can make sense to put them in own repo

    • +
+

A project directory can look something like this:

+
project_name/
+├── README.md             # overview of the project
+├── data/                 # data files used in the project
+│   ├── README.md         # describes where data came from
+│   └── sub-folder/       # may contain subdirectories
+├── processed_data/       # intermediate files from the analysis
+├── manuscript/           # manuscript describing the results
+├── results/              # results of the analysis (data, tables, figures)
+├── src/                  # contains all code in the project
+│   ├── LICENSE           # license for your code
+│   ├── requirements.txt  # software requirements and dependencies
+│   └── ...
+└── doc/                  # documentation for your project
+    ├── index.rst
+    └── ...
+
+
+
+
+
+

Tracking source code, data, and results

+
    +

  • All code is version controlled and goes in the src/ or source/ directory

    • +

  • Include appropriate LICENSE file and information on software requirements

    • +

  • You can also version control data files or input files under data/

    • +

  • If data files are too large (or sensitive) to track, untrack them using .gitignore

    • +

  • Intermediate files from the analysis are kept in processed_data/

    • +

  • Consider using Git tags to mark specific versions of results (version +submitted to a journal, dissertation version, poster version, etc.):

    +
    $ git tag -a thesis-submitted -m "this is the submitted version of my thesis"
+
    +
    +
    • +
+ +
+
+
+

Reproducible publications

+
    +

  • Git can be used to collaborate on manuscripts written in, e.g., LaTeX and other text-based formats but other tools exist:

    +
      +

    • Overleaf: an online, collaborative LaTeX editor (has Git integration)

      • +

    • Authorea: collaborative platform for preprints (apparently also has Git integration)

      • +

    • HackMD: an online collaborative Markdown editor (has Git integration)

      • +

    • Manuscripts.io: a collaborative authoring tool that support scientific content and reproducibility.

      • +

    • Google Docs can be a good alternative

      • +
    +
    • +

  • Many tools exist to assist in making scholarly output reproducible:

    +
      +

    • rrtools: instructions, templates, and functions for writing a reproducible article or report with R.

      • +

    • Jupyter Notebooks: web-based computational environment for creating code and text based notebooks that can be used as, see also our Jupyter lesson later in this workshop. +supplementary material for articles.

      • +

    • Binder: makes a repository with Jupyter notebooks available in an executable environment (discussed later in the Jupyter lesson).

      • +

    • “Research compendia”: a set of good practices for +reproducible data analysis in R, but much is transferable to other languages.

Keypoints

+
    +

  • An organized project directory structure helps with reproducibility.

    • +

  • Reproducibility makes work easier for the next person working on the project - and that might be you in a few years!

+

Recording computational steps

+
+

Questions

+
    +

  • You have some steps that need to be run to do your work. How do you +actually run them? Does it rely on your own memory and work, or is it +reproducible? How do you communicate the steps for future you and others?

    • +

  • How can we create a reproducible workflow?

    • +

  • When to use scientific workflow management systems.

Several steps from input data to result

+

The following material is partly derived from a HPC Carpentry lesson.

+

In this episode, we will use an example +project which finds most frequent +words in books and plots the result from those statistics. In this example we +wish to:

+
    +

  1. Analyze word frequencies using statistics/count.py +for 4 books +(they are all in the data directory).

    2. +

  2. Plot a histogram using plot/plot.py.

    3. +
+
+From book to word counts to plot +
+

Example (for one book only):

+
$ python statistics/count.py data/isles.txt > statistics/isles.data
+$ python plot/plot.py --data-file statistics/isles.data --plot-file plot/isles.png
+
+
+
+

Discussion

+

We have two steps and 4 books. But imagine having 4 steps and processing 500 books. +Can you relate? Are you using similar setups in your research? How do you record them?

+
+
+

Kitchen analogy

+
+Busy kitchen +
+

Now we have many similar meals to prepare and possibly many chefs +present (cores) and workflow tools can help us to plan and document the steps +and run them efficiently. [Midjourney, CC-BY-NC 4.0]

Exercise

+
+

Exercise preparation

+

The exercise (below) and pre-exercise discussion uses a simple +word-count repository +(https://github.com/coderefinery/word-count). We should clone the +repository already to prepare to work on it.

+

You could do the exercise either on your own computer, or the Binder +cloud service:

+

On your own computer:

+
    +

  • Activate the coderefinery conda environment with conda activate coderefinery.

    • +

  • Clone the word-count repository:

    +
    $ git clone https://github.com/coderefinery/word-count.git
+
    +
    +
    • +
+

On Binder: +We can also use the cloud service Binder to make sure +we all have the same computing environment. This is interesting from a +reproducible research point of view and it’s explained further in the Jupyter +lesson how this is even +possible.

+
    +

  • Go to https://github.com/coderefinery/word-count and click on the “launch binder” badge in the README.

    • +

  • Once it get started, you can open a new Terminal from the new menu (top right) and select Terminal.

    • +
+
+
+

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

    • +
+ +
+
+

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),

+rule count_words:

+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

    10. +
+ +
+
+
+

Why Snakemake?

+
    +

  • Gentle learning curve.

    • +

  • Free, open-source, and installs easily via conda or pip.

    • +

  • Cross-platform (Windows, MacOS, Linux) and compatible with all HPC schedulers: +same workflow works without modification and scales appropriately whether on a laptop or cluster.

    • +

  • Heavily used in bioinformatics, but is completely general.

    • +

  • Is is possible to define isolated software environments per rule, see here.

    • +

  • Also possible to run workflows in Docker or Apptainer containers.

    • +

  • Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up.

    • +

  • If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel.

    • +

  • Nice functionality for archiving the workflow, see: the official documentation

    • +
+
+
+

Similar tools

+ +
+
+

Visualizing the workflow

+

We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the --dag option, which will output the DAG in dot language.

+

Note: This requires the Graphviz software, +which can be installed by conda install graphviz. It’s not necessary to +run this step yourself.

+
$ snakemake -j 1 --dag | dot -Tpng > dag.png
+
+
+

Rules that have yet to be completed are indicated with solid outlines, while already completed rules are indicated with dashed outlines.

Tools and what problems they try to solve

+

Conda, Anaconda, pip, virtualenv, Pipenv, pyenv, Poetry, requirements.txt, +environment.yml, renv, …, these tools try to solve the following problems:

+
    +

  • Defining a specific set of dependencies, possibly with well defined versions

    • +

  • Installing those dependencies mostly automatically

    • +

  • Recording the versions for all dependencies

    • +

  • Isolate environments

    +
      +

    • On your computer for projects so they can use different software

      • +

    • Isolate environments on computers with many users (and allow self-installations)

      • +
    +
    • +

  • Using different Python/R versions per project

    • +

  • Provide tools and services to share packages

    • +
+

Isolated environments are also useful because they help you make sure +that you know your dependencies!

+

If things go wrong, you can delete and re-create - much better +than debugging. The more often you re-create your environment, the +more reproducible it is.

Exercises

+
+

(optional) Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+

Answer in the collaborative document:

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click
+  - python

+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +

(optional) Dependencies-2: Create a time-capsule for the future

+

Now it is time to create your own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml

What is a container?

+

Imagine if you didn’t have to install things yourself, but instead you could +get a computer with the exact software for a task pre-installed? Containers +effectively do that, with various advantages and disadvantages. They are +like an entire operating system with software installed, all in one file,

+He said, then we will ship your machine. And that's how Docker was born. +

    • +

  • Container definition files <-> like a blueprint to build a kitchen with all +utensils in which the recipe can be prepared.

From definition files to container images to containers

+
    +

  • Containers can be built to bundle all the necessary ingredients (data, code, environment, operating system).

    • +

  • A container image is like a piece of paper with all the operating system on it. When you run it, +a transparent sheet is placed on top to form a container. The container runs and writes only on +that transparent sheet (and what other mounts have been layered on top). When you are done, +transparency is thrown away. It can be repeated as often as you want, and base is always the same.

    • +

  • Definition files (e.g. Dockerfile or Singularity definition file) are text +files that contain a series of instructions to build container images.

    • +
+
+
+

You may have use for containers in different ways

+
    +

  • Installing a certain software is tricky, or not supported for your operating system? -> See if an image is available and run the software from a container instead!

    • +

  • You want to make sure your colleagues are using the same environment for running your code? -> Provide them an image of your container!

    +
      +

    • If this does not work, because they are using a different architecture than you do? -> Provide a definition file for them to build the image suitable to their computers. This does not create the exact environment as you have, but in most cases similar enough.

      • +
    +
    • +
+
+
+

The container recipe

+

Here is an example of a Singularity definition file (reference):

+
Bootstrap: docker
+From: ubuntu:20.04
+
+%post
+    apt-get -y update
+    apt-get -y install cowsay lolcat
+
+%environment
+    export LC_ALL=C
+    export PATH=/usr/games:$PATH
+
+%runscript
+    date | cowsay | lolcat
+
+
+

Popular container implementations:

+ +

They are to some extent interoperable:

+
    +

  • podman is very close to Docker

    • +

  • Docker images can be converted to Singularity/Apptainer images

    • +

  • Singularity Python can convert Dockerfiles to Singularity definition files

    • +
+
+
+
+

Pros and cons of containers

+

Containers are popular for a reason - they solve a number of +important problems:

+
    +

  • Allow for seamlessly moving workflows across different platforms.

    • +

  • Can solve the “works on my machine” situation.

    • +

  • For software with many dependencies, in turn with its own dependencies, +containers offer possibly the only way to preserve the +computational experiment for future reproducibility.

    • +

  • A mechanism to “send the computer to the data” when data is too

    • +

  • Installing software into a file instead of into your computer (removing +a file is often easier than uninstalling software if you suddenly regret an +installation)

    • +
+

However, containers may also have some drawbacks:

+
    +

  • Can be used to hide away software installation problems and thereby +discourage good software development practices.

    • +

  • Instead of “works on my machine” problem: “works only in this container” problem?

    • +

  • They can be difficult to modify (this is the focus of an exercise below)

    • +

  • Container images can become large

    • +
+
+

Danger

+

Use only official and trusted images! Not all images can be trusted! There +have been examples of contaminated images so investigate before using images +blindly. Apply same caution as installing software packages from untrusted +package repositories.

+
+
+
+
+

Where can one share or find images?

+ +
+
+
+

Exercises

+
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

(optional) Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash

Objectives

+
    +

  • Understand when tools discussed in this episode can be useful

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching/discussion

    • +
+
+

This episode presents a lot of different tools and opportunities for your research software project. +However, you will not always need all of them. As with so many things, it again depends on your project.

+
+

Important for every project

+
    +

  • Clear file structure for your project

    • +

  • At least consider the possibility that someone, maybe you may want to reproduce your work

    +
      +

    • Can you do something (small) to make it easier?

      • +

    • If you have ideas, but no time: add an issue to your repository; maybe someone else wants to help.

      • +
    +
    • +
+
+
+

Workflow tools will maybe make sense in the future

+
    +

  • In many cases, it is probably not needed

    • +

  • You will want to consider workflow tools:

    +
      +

    • When processing many files with many steps

      • +

    • Steps or files may change

      • +

    • Your main script, connecting your steps gets very long

      • +

    • …

      • +
    +
    • +
+
+
+

When should I worry about dependencies?

+
    +

  • Your code depends on multiple other packages

    • +

  • You want to avoid questions like: “What do I need to install to run your code”

    • +

  • You want help yourself running your code

    +
      +

    • After a few years

      • +

    • On a different computer

      • +

    • …

      • +
    +
    • +
+
+
+

Containers seem amazing, but do I have use for them?

+
    +

  • Maybe not yet, but knowing that you can …

    +
      +

    • Run Linux tools on your Windows computer

      • +

    • Run different versions of same software on your computer

      • +

    • Follow the “easy installation instructions” for an operating system that is not your own

      • +

    • Get a fully configured environment instead of only installing a tool

      • +

    • Share your setup and configurations with others +… can be very beneficial :)

Detailed day schedule

+

Two example schedules for this lesson:

+

This is the planned schedule for the workshop in September 2023 (2 hours and 5 minutes including 10 min break) ; note that for this workshop, sharing code and data was moved to social coding lesson:

+ +

This was the schedule at workshop in March 2023 (2 hours and 15 minutes including 2x 10 min break):

+ +
+
+

Why we teach this lesson

+

Reproducibility in research is something that publishers, funding agencies, universities, +research leaders and the general public worries about and much is being written about it. +It is also something that researchers care deeply about - this lesson is typically one of the +most popular lessons in the pre-workshop survey.

+

Even though most PhD students, postdocs and researchers (i.e. typical workshop participants) +know about the importance of reproducibility in research, they often lack both a general +overview of what different aspects there are to reproducibility, and the knowledge of +specific tools that can be used for improving reproducibility.

+

Many participants may not adhere to good practices when organizing their projects, +and the “Organizing your projects” episode is meant to encourage participants to +structure their projects better. This may be obvious to some participants but it +doesn’t harm to preach to the choir.

+

Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people’s code to run), they +often don’t know or use good practices when it comes to recording dependencies. +Most participants also don’t use isolated environments for different projects and +don’t know why that can be important. +The episode “Recording dependencies” tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager.

+

Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +“Recording environments” introduces the concept of containers, and the optional +episode “Creating and sharing a container image” goes into details.

+

Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of “scientific workflows”, +and that there actually exist tools that help make such workflows reproducible. +The episode “Recording computational steps” introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible.

+
+
+

How to teach this lesson

+
+

How to start

+

Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we’re going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers).

+
+
+

Focus on concepts, and when to use which tool

+

Try to explain better what the different tools are useful for, but don’t go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem.

+
+
+
+

Typical pitfalls

+
+

Indentation in Snakefiles

+
    +

  • the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn’t matter +This works:

    • +
+
rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+
+

but this doesn’t work:

+
rule all:
+    input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+

nor this:

+
rule all:
+input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+
+
+
+

Field reports

+
+

2022 September

+

We used the strategy “absolutely minimal introductions, most time +for exercise”. Overall, it was probably the right thing to do since +there is so little time and so much to cover.

+

There wasn’t enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode.

+

The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn’t really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day.

Objectives

+
    +

  • Understand when tools discussed in this episode can be useful

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching/discussion

    • +
+
+

This episode presents a lot of different tools and opportunities for your research software project. +However, you will not always need all of them. As with so many things, it again depends on your project.

+
+

Important for every project

+
    +

  • Clear file structure for your project

    • +

  • At least consider the possibility that someone, maybe you may want to reproduce your work

    +
      +

    • Can you do something (small) to make it easier?

      • +

    • If you have ideas, but no time: add an issue to your repository; maybe someone else wants to help.

      • +
    +
    • +
+
+
+

Workflow tools will maybe make sense in the future

+
    +

  • In many cases, it is probably not needed

    • +

  • You will want to consider workflow tools:

    +
      +

    • When processing many files with many steps

      • +

    • Steps or files may change

      • +

    • Your main script, connecting your steps gets very long

      • +

    • …

      • +
    +
    • +
+
+
+

When should I worry about dependencies?

+
    +

  • Your code depends on multiple other packages

    • +

  • You want to avoid questions like: “What do I need to install to run your code”

    • +

  • You want help yourself running your code

    +
      +

    • After a few years

      • +

    • On a different computer

      • +

    • …

      • +
    +
    • +
+
+
+

Containers seem amazing, but do I have use for them?

+
    +

  • Maybe not yet, but knowing that you can …

    +
      +

    • Run Linux tools on your Windows computer

      • +

    • Run different versions of same software on your computer

      • +

    • Follow the “easy installation instructions” for an operating system that is not your own

      • +

    • Get a fully configured environment instead of only installing a tool

      • +

    • Share your setup and configurations with others +… can be very beneficial :)

Recording computational steps

+
+

Questions

+
    +

  • You have some steps that need to be run to do your work. How do you +actually run them? Does it rely on your own memory and work, or is it +reproducible? How do you communicate the steps for future you and others?

    • +

  • How can we create a reproducible workflow?

    • +

  • When to use scientific workflow management systems.

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching

    • +

  • 20 min exercises

    • +
+
+
+

Several steps from input data to result

+

The following material is partly derived from a HPC Carpentry lesson.

+

In this episode, we will use an example +project which finds most frequent +words in books and plots the result from those statistics. In this example we +wish to:

+
    +

  1. Analyze word frequencies using statistics/count.py +for 4 books +(they are all in the data directory).

    2. +

  2. Plot a histogram using plot/plot.py.

    3. +
+
+From book to word counts to plot +
+

Example (for one book only):

+
$ python statistics/count.py data/isles.txt > statistics/isles.data
+$ python plot/plot.py --data-file statistics/isles.data --plot-file plot/isles.png
+
+
+
+

Discussion

+

We have two steps and 4 books. But imagine having 4 steps and processing 500 books. +Can you relate? Are you using similar setups in your research? How do you record them?

+
+
+

Kitchen analogy

+
+Busy kitchen +
+

Now we have many similar meals to prepare and possibly many chefs +present (cores) and workflow tools can help us to plan and document the steps +and run them efficiently. [Midjourney, CC-BY-NC 4.0]

+
+

Exercise

+
+

Exercise preparation

+

The exercise (below) and pre-exercise discussion uses a simple +word-count repository +(https://github.com/coderefinery/word-count). We should clone the +repository already to prepare to work on it.

+

You could do the exercise either on your own computer, or the Binder +cloud service:

+

On your own computer:

+
    +

  • Activate the coderefinery conda environment with conda activate coderefinery.

    • +

  • Clone the word-count repository:

    +
    $ git clone https://github.com/coderefinery/word-count.git
+
    +
    +
    • +
+

On Binder: +We can also use the cloud service Binder to make sure +we all have the same computing environment. This is interesting from a +reproducible research point of view and it’s explained further in the Jupyter +lesson how this is even +possible.

+
    +

  • Go to https://github.com/coderefinery/word-count and click on the “launch binder” badge in the README.

    • +

  • Once it get started, you can open a new Terminal from the new menu (top right) and select Terminal.

    • +
+
+
+

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

    • +
+ +
+
+

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

    10. +
+ +
+
+
+

Why Snakemake?

+
    +

  • Gentle learning curve.

    • +

  • Free, open-source, and installs easily via conda or pip.

    • +

  • Cross-platform (Windows, MacOS, Linux) and compatible with all HPC schedulers: +same workflow works without modification and scales appropriately whether on a laptop or cluster.

    • +

  • Heavily used in bioinformatics, but is completely general.

    • +

  • Is is possible to define isolated software environments per rule, see here.

    • +

  • Also possible to run workflows in Docker or Apptainer containers.

    • +

  • Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up.

    • +

  • If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel.

    • +

  • Nice functionality for archiving the workflow, see: the official documentation

    • +
+
+
+

Similar tools

+ +
+
+

Visualizing the workflow

+

We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the --dag option, which will output the DAG in dot language.

+

Note: This requires the Graphviz software, +which can be installed by conda install graphviz. It’s not necessary to +run this step yourself.

+
$ snakemake -j 1 --dag | dot -Tpng > dag.png
+
+
+

Rules that have yet to be completed are indicated with solid outlines, while already completed rules are indicated with dashed outlines.

This may be obvious to some participants but it +doesn't harm to preach to the choir. + +Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people's code to run), they +often don't know or use good practices when it comes to recording dependencies. +Most participants also don't use isolated environments for different projects and +don't know why that can be important. +The episode "Recording dependencies" tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager. + +Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +"Recording environments" introduces the concept of containers, and the optional +episode "Creating and sharing a container image" goes into details. + +Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of "scientific workflows", +and that there actually exist tools that help make such workflows reproducible. +The episode "Recording computational steps" introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible. + + +## How to teach this lesson + +### How to start + +Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this.

In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem. + + +## Typical pitfalls + +### Indentation in Snakefiles + +- the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn't matter +This works: +```python +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` +but this doesn't work: +```python +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` +nor this: +```python +rule all: +input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` + + +## Field reports + +### 2022 September + +We used the strategy "absolutely minimal introductions, most time +for exercise".

Clone the example to your computer: `$ git clone https://github.com/coderefinery/word-count.git` +2. Study the Snakefile. How does it know what to do first and what to do then? +3. Try to run it. Since version 5.11 one needs to specify number of cores (or + jobs) using `-j`, `--jobs` or `--cores`: + ```console + $ snakemake --delete-all-output -j 1 + $ snakemake -j 1 + ``` + The `--delete-all-output` part makes sure that we remove all generated files before we start. +4. Try running `snakemake` again and observe that and discuss why it refused to rerun all steps: + ```console + $ snakemake -j 1 + + Building DAG of jobs... + Nothing to be done (all requested files are present and up to date). + ``` +5. Make a tiny modification to the plot.py script and run `$ snakemake -j 1` again and observe how it will only re-run the plot steps. +6. Make a tiny modification to one of the books and run `$ snakemake -j 1` again and observe how it only regenerates files for this book. +7. Discuss possible advantages compared to a scripted solution. +8. **Question for R developers**: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in + the [Snakefile](https://github.com/coderefinery/word-count/blob/main/Snakefile) would you have to modify so that it uses your R code? +9. If you make changes to the Snakefile, validate it using `$ snakemake --lint`. + +```{solution} +- 2: Start with "all" and look what it depends on. Now search for rules that + have these as output. Look for their inputs and search where they + are produced. In other words, search backwards and build a graph of + dependencies. This is what Snakemake does. +- 4: It can see that outputs are newer than inputs. It will only regenerate + outputs if they are not there or if the inputs or scripts have changed. +- 7: It only generates steps and outputs that are missing or outdated. The workflow + does not run everything every time. In other words if you notice a problem or update information + "half way" in the analysis, it will only re-run what needs to be re-run. Nothing more, nothing less. + Another advantage is that it can distribute tasks to multiple cores, off-load work to supercomputers, + offers more fine-grained control over environments, and more. +- 8: Probably only the two lines containing "shell". +``` +```` + + +## Why [Snakemake](https://snakemake.readthedocs.io/)? + +- Gentle learning curve. +- Free, open-source, and installs easily via conda or pip. +- Cross-platform (Windows, MacOS, Linux) and compatible with all HPC schedulers: + same workflow works without modification and scales appropriately whether on a laptop or cluster. +- [Heavily used in bioinformatics](https://twitter.com/carl_witt/status/1103951128046301185), but is completely general. +- Is is possible to define isolated software environments per rule, see [here](https://github.com/coderefinery/word-count/blob/f4ca47440751dd2c65f55fef1a8d9f181ecdd2f6/Snakefile#L15). +- Also possible to run workflows in Docker or Apptainer containers. +- Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up. +- If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel. +- Nice functionality for archiving the workflow, see: [the official documentation](https://snakemake.readthedocs.io/en/stable/snakefiles/deployment.html#sustainable-and-reproducible-archiving) + + +## Similar tools + +- [Make](https://www.gnu.org/software/make/) +- [Nextflow](https://www.nextflow.io/) +- [Task](https://taskfile.dev/) +- [Common Workflow Language](https://www.commonwl.org/) +- Many [specialized frameworks](https://github.com/common-workflow-language/common-workflow-language/wiki/Existing-Workflow-systems) exist. +- [Book on building reproducible analytical pipelines with R](https://raps-with-r.dev/) + + +## Visualizing the workflow + +We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the `--dag` option, which will output the DAG in `dot` language. + +**Note**: This requires the [Graphviz software](https://www.graphviz.org/), +which can be installed by `conda install graphviz`.

Tools and what problems they try to solve

+

Conda, Anaconda, pip, virtualenv, Pipenv, pyenv, Poetry, requirements.txt, +environment.yml, renv, …, these tools try to solve the following problems:

+
    +

  • Defining a specific set of dependencies, possibly with well defined versions

    • +

  • Installing those dependencies mostly automatically

    • +

  • Recording the versions for all dependencies

    • +

  • Isolate environments

    +
      +

    • On your computer for projects so they can use different software

      • +

    • Isolate environments on computers with many users (and allow self-installations)

      • +
    +
    • +

  • Using different Python/R versions per project

    • +

  • Provide tools and services to share packages

    • +
+

Isolated environments are also useful because they help you make sure +that you know your dependencies!

+

If things go wrong, you can delete and re-create - much better +than debugging. The more often you re-create your environment, the +more reproducible it is.

Exercises

+
+

Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+

Answer in the collaborative document:

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click
+  - python
+  - pip
+  - pip:
+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4

+  - python=3.8
+  - pip

+    - git+https://github.com/anotheruser/anotherproject.git@sometag
+
    +
    +

    E: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4

+
    +
    +
    + +
    • +
+
+
+

Dependencies-2: Create a time-capsule for the future

+

Now we will demo creating our own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+
+
+

What is a container?

+

Imagine if you didn’t have to install things yourself, but instead you could +get a computer with the exact software for a task pre-installed? Containers +effectively do that, with various advantages and disadvantages. They are +like an entire operating system with software installed, all in one file,

+
+He said, then we will ship your machine. And that's how Docker was born. +

From definition files to container images to containers

+
    +

  • Containers can be built to bundle all the necessary ingredients (data, code, environment, operating system).

    • +

  • A container image is like a piece of paper with all the operating system on it. When you run it, +a transparent sheet is placed on top to form a container. The container runs and writes only on +that transparent sheet (and what other mounts have been layered on top). When you are done, +transparency is thrown away. It can be repeated as often as you want, and base is always the same.

    • +

  • Definition files (e.g. Dockerfile or Singularity definition file) are text +files that contain a series of instructions to build container images.

    • +
+
+
+

You may have use for containers in different ways

+
    +

  • Installing a certain software is tricky, or not supported for your operating system? -> See if an image is available and run the software from a container instead!

    • +

  • You want to make sure your colleagues are using the same environment for running your code? -> Provide them an image of your container!

    +
      +

    • If this does not work, because they are using a different architecture than you do? -> Provide a definition file for them to build the image suitable to their computers. This does not create the exact environment as you have, but in most cases similar enough.

      • +
    +
    • +
+
+
+

The container recipe

+

Here is an example of a Singularity definition file (reference):

+
Bootstrap: docker
+From: ubuntu:20.04
+
+%post
+    apt-get -y update
+    apt-get -y install cowsay lolcat
+
+%environment
+    export LC_ALL=C
+    export PATH=/usr/games:$PATH
+
+%runscript
+    date | cowsay | lolcat
+
+
+

Popular container implementations:

+ +

They are to some extent interoperable:

+
    +

  • podman is very close to Docker

    • +

  • Docker images can be converted to Singularity/Apptainer images

    • +

  • Singularity Python can convert Dockerfiles to Singularity definition files

    • +
+
+
+
+

Pros and cons of containers

+

Containers are popular for a reason - they solve a number of +important problems:

+
    +

  • Allow for seamlessly moving workflows across different platforms.

    • +

  • Can solve the “works on my machine” situation.

    • +

  • For software with many dependencies, in turn with its own dependencies, +containers offer possibly the only way to preserve the +computational experiment for future reproducibility.

    • +

  • A mechanism to “send the computer to the data” when data is too

    • +

  • Installing software into a file instead of into your computer (removing +a file is often easier than uninstalling software if you suddenly regret an +installation)

    • +
+

However, containers may also have some drawbacks:

+
    +

  • Can be used to hide away software installation problems and thereby +discourage good software development practices.

    • +

  • Instead of “works on my machine” problem: “works only in this container” problem?

    • +

  • They can be difficult to modify (this is the focus of an exercise below)

    • +

  • Container images can become large

    • +
+
+

Danger

+

Use only official and trusted images! Not all images can be trusted! There +have been examples of contaminated images so investigate before using images +blindly. Apply same caution as installing software packages from untrusted +package repositories.

+
+
+
+
+

Where can one share or find images?

+ +
+
+
+

Exercises

+
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

(optional) Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash
+
    +

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+

Answer in the collaborative document:

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click
+  - python
+  - pip

+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4

+    - git+https://github.com/anotheruser/anotherproject.git@sometag
+
    +
    +

    E: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1

Dependencies-2: Create a time-capsule for the future

+

Now we will demo creating our own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

Detailed day schedule

+

Two example schedules for this lesson:

+

This is the planned schedule for the workshop in September 2023 (2 hours and 5 minutes including 10 min break) ; note that for this workshop, sharing code and data was moved to social coding lesson:

+ +

This was the schedule at workshop in March 2023 (2 hours and 15 minutes including 2x 10 min break):

+ +
+
+

Why we teach this lesson

+

Reproducibility in research is something that publishers, funding agencies, universities, +research leaders and the general public worries about and much is being written about it. +It is also something that researchers care deeply about - this lesson is typically one of the +most popular lessons in the pre-workshop survey.

+

Even though most PhD students, postdocs and researchers (i.e. typical workshop participants) +know about the importance of reproducibility in research, they often lack both a general +overview of what different aspects there are to reproducibility, and the knowledge of +specific tools that can be used for improving reproducibility.

+

Many participants may not adhere to good practices when organizing their projects, +and the “Organizing your projects” episode is meant to encourage participants to +structure their projects better. This may be obvious to some participants but it +doesn’t harm to preach to the choir.

+

Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people’s code to run), they +often don’t know or use good practices when it comes to recording dependencies. +Most participants also don’t use isolated environments for different projects and +don’t know why that can be important. +The episode “Recording dependencies” tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager.

+

Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +“Recording environments” introduces the concept of containers, and the optional +episode “Creating and sharing a container image” goes into details.

+

Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of “scientific workflows”, +and that there actually exist tools that help make such workflows reproducible. +The episode “Recording computational steps” introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible.

+
+
+

How to teach this lesson

+
+

How to start

+

Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we’re going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers).

+
+
+

Focus on concepts, and when to use which tool

+

Try to explain better what the different tools are useful for, but don’t go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem.

+
+
+
+

Typical pitfalls

+
+

Indentation in Snakefiles

+
    +

  • the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn’t matter +This works:

    • +
+
rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+
+

but this doesn’t work:

+
rule all:
+    input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+

nor this:

+
rule all:
+input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+
+
+
+

Field reports

+
+

2022 September

+

We used the strategy “absolutely minimal introductions, most time +for exercise”. Overall, it was probably the right thing to do since +there is so little time and so much to cover.

+

There wasn’t enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode.

+

The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn’t really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day.

Reproducible research - Preparing code to be usable by you and others in the future

+

Have you ever spent days trying to repeat the results from few weeks or months +ago? Or you have to do paper revisions, but you just can’t get the results to +match up? It’s unpleasant for both you and science.

+

In this lesson we will explore different methods and tools for better +reproducibility in research software and data. We will demonstrate how version +control, workflows, containers, and package managers can be used to record +reproducible environments and computational steps for our future selves.

+
+

A scary anecdote

+
    +

  • A group of researchers obtain great results and submit their work to a high-profile journal.

    • +

  • Reviewers ask for new figures and additional analysis.

    • +

  • The researchers start working on revisions and generate modified figures, but find inconsistencies with old figures.

    • +

  • The researchers can’t find some of the data they used to generate the original results, and +can’t figure out which parameters they used when running their analyses.

    • +

  • The manuscript is still languishing in the drawer …

    • +
+
+
+
+

Why talking about reproducible research?

+

A 2016 +survey +in Nature revealed that irreproducible experiments are a problem across all +domains of science:

+
+reproduciblity Nature +
+

This study is now few years old but the highlighted problem did not get +smaller.

+
+
+
+

Levels of reproducibility

+

A published article is like the top of a pyramid. It rests on multiple +levels that each contributes to its reproducibility.

+

Organizing your projects

+
+

Objectives

+
    +

  • Get an overview on how to organize research projects

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching incl. discussions

    • +
+
+

One of the first steps to make your work reproducible is to organize your projects well. +Let’s go over some of the basic things which people have found to work (and not to work).

+
+

Directory structure for projects

+
    +

  • Project files in a single folder

    • +

  • Different projects should have separate folders

    • +

  • Use consistent and informative directory structure

    +
      +

    • Avoid spaces in directory and file names – it is uglier for humans but handy for computers.

      • +
    +
    • +

  • If you need to separate public/private, you can put them in public and private Git repos

    +
      +

    • If you need to separate public/secret, use .gitignore or a separate folder that’s not in Git

      • +
    +
    • +

  • Add a README file to describe the project and instructions on reproducing the results

    • +

  • If a software is reused in several projects it can make sense to put them in own repo

    • +
+

A project directory can look something like this:

+
project_name/
+├── README.md             # overview of the project
+├── data/                 # data files used in the project
+│   ├── README.md         # describes where data came from
+│   └── sub-folder/       # may contain subdirectories
+├── processed_data/       # intermediate files from the analysis
+├── manuscript/           # manuscript describing the results
+├── results/              # results of the analysis (data, tables, figures)
+├── src/                  # contains all code in the project
+│   ├── LICENSE           # license for your code
+│   ├── requirements.txt  # software requirements and dependencies
+│   └── ...
+└── doc/                  # documentation for your project
+    ├── index.rst
+    └── ...
+
+
+
+
+
+

Tracking source code, data, and results

+
    +

  • All code is version controlled and goes in the src/ or source/ directory

    • +

  • Include appropriate LICENSE file and information on software requirements

    • +

  • You can also version control data files or input files under data/

    • +

  • If data files are too large (or sensitive) to track, untrack them using .gitignore

    • +

  • Intermediate files from the analysis are kept in processed_data/

    • +

  • Consider using Git tags to mark specific versions of results (version +submitted to a journal, dissertation version, poster version, etc.):

    +
    $ git tag -a thesis-submitted -m "this is the submitted version of my thesis"
+
    +
    +
    • +
+ +
+
+
+

Discussion on reproducibility

+
+

Discuss in collaborative document

+

How do you collaborate on writing academic papers?

+
- Are you using version control for academic papers?
+  - ...
+  - ...
+  - (share your experience)
+
+- How do you handle collaborative issues e.g. conflicting changes?
+  - ...
+  - ...
+  - (share your experience)
+
+
+
+

Please write or discuss your ideas before opening solution!

+
+ +
+
+
+

Reproducible publications

+
    +

  • Git can be used to collaborate on manuscripts written in, e.g., LaTeX and other text-based formats but other tools exist:

    +
      +

    • Overleaf: an online, collaborative LaTeX editor (has Git integration)

      • +

    • Authorea: collaborative platform for preprints (apparently also has Git integration)

      • +

    • HackMD: an online collaborative Markdown editor (has Git integration)

      • +

    • Manuscripts.io: a collaborative authoring tool that support scientific content and reproducibility.

      • +

    • Google Docs can be a good alternative

      • +
    +
    • +

  • Many tools exist to assist in making scholarly output reproducible:

    +
      +

    • rrtools: instructions, templates, and functions for writing a reproducible article or report with R.

      • +

    • Jupyter Notebooks: web-based computational environment for creating code and text based notebooks that can be used as, see also our Jupyter lesson later in this workshop. +supplementary material for articles.

      • +

    • Binder: makes a repository with Jupyter notebooks available in an executable environment (discussed later in the Jupyter lesson).

      • +

    • “Research compendia”: a set of good practices for +reproducible data analysis in R, but much is transferable to other languages.

      • +

Keypoints

+
    +

  • An organized project directory structure helps with reproducibility.

    • +

  • Reproducibility makes work easier for the next person working on the project - and that might be you in a few years!

Reproducible research - Preparing code to be usable by you and others in the future

+

Have you ever spent days trying to repeat the results from few weeks or months +ago? Or you have to do paper revisions, but you just can’t get the results to +match up? It’s unpleasant for both you and science.

+

In this lesson we will explore different methods and tools for better +reproducibility in research software and data. We will demonstrate how version +control, workflows, containers, and package managers can be used to record +reproducible environments and computational steps for our future selves.

+
+

Learning outcomes

+
+
By the end of this lesson, learners should:
    +

  • be able to apply well organized directory structure for their project

    • +

  • remember the FAIR principles

    • +

  • understand that code can have dependencies, and know how to document them

    • +

  • if a computational studies contains several steps, be able to document them

    • +

  • know about use cases for containers

    • +

  • knowing the pros and cons of manual documentation vs. scripted automation vs. workflow management

    • +
+
+
+
+
+

Prerequisites

+

You need to install +Git, Python, and Snakemake.

A scary anecdote

+
    +

  • A group of researchers obtain great results and submit their work to a high-profile journal.

    • +

  • Reviewers ask for new figures and additional analysis.

    • +

  • The researchers start working on revisions and generate modified figures, but find inconsistencies with old figures.

    • +

  • The researchers can’t find some of the data they used to generate the original results, and +can’t figure out which parameters they used when running their analyses.

    • +

  • The manuscript is still languishing in the drawer …

    • +
+
+
+
+

Why talking about reproducible research?

+

A 2016 +survey +in Nature revealed that irreproducible experiments are a problem across all +domains of science:

+
+reproduciblity Nature +
+

This study is now few years old but the highlighted problem did not get +smaller.

+
+
+
+

Levels of reproducibility

+

A published article is like the top of a pyramid. It rests on multiple +levels that each contributes to its reproducibility.

+
+Reproducibility pyramid +
+

[Steeves, Vicky (2017) in “Reproducibility Librarianship,” Collaborative Librarianship: Vol. 9: Iss. 2, Article 4. +Available at: https://digitalcommons.du.edu/collaborativelibrarianship/vol9/iss2/4]

+

This also means that you can think about it from the beginning of your research life cycle!

+
+
+

Discuss in collaborative document or with your team members

+
- What are your experiences re-running or adjusting a script or a figure you
+  created few months ago?
+  - ...
+  - ...
+  - (share your experience)
+
+- Have you continued working from a previous student's
+  script/code/plot/notebook? What were the biggest challenges?
+  - ...
+  - ...
+  - (share your experience, but constructively)
+
+
+
+

+
+

Organizing your projects

+
+

Objectives

+
    +

  • Get an overview on how to organize research projects

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching incl. discussions

    • +
+
+

One of the first steps to make your work reproducible is to organize your projects well. +Let’s go over some of the basic things which people have found to work (and not to work).

+
+

Directory structure for projects

+
    +

  • Project files in a single folder

    • +

  • Different projects should have separate folders

    • +

  • Use consistent and informative directory structure

    +
      +

    • Avoid spaces in directory and file names – it is uglier for humans but handy for computers.

      • +
    +
    • +

  • If you need to separate public/private, you can put them in public and private Git repos

    +
      +

    • If you need to separate public/secret, use .gitignore or a separate folder that’s not in Git

      • +
    +
    • +

  • Add a README file to describe the project and instructions on reproducing the results

    • +

  • If a software is reused in several projects it can make sense to put them in own repo

    • +
+

A project directory can look something like this:

+
project_name/
+├── README.md             # overview of the project
+├── data/                 # data files used in the project
+│   ├── README.md         # describes where data came from
+│   └── sub-folder/       # may contain subdirectories
+├── processed_data/       # intermediate files from the analysis
+├── manuscript/           # manuscript describing the results
+├── results/              # results of the analysis (data, tables, figures)
+├── src/                  # contains all code in the project
+│   ├── LICENSE           # license for your code
+│   ├── requirements.txt  # software requirements and dependencies
+│   └── ...
+└── doc/                  # documentation for your project
+    ├── index.rst
+    └── ...
+
+
+
+
+
+

Tracking source code, data, and results

+
    +

  • All code is version controlled and goes in the src/ or source/ directory

    • +

  • Include appropriate LICENSE file and information on software requirements

    • +

  • You can also version control data files or input files under data/

    • +

  • If data files are too large (or sensitive) to track, untrack them using .gitignore

    • +

  • Intermediate files from the analysis are kept in processed_data/

    • +

  • Consider using Git tags to mark specific versions of results (version +submitted to a journal, dissertation version, poster version, etc.):

    +
    $ git tag -a thesis-submitted -m "this is the submitted version of my thesis"
+
    +
    +
    • +
+ +
+
+
+

Discussion on reproducibility

+
+

Discuss in collaborative document

+

How do you collaborate on writing academic papers?

+
- Are you using version control for academic papers?
+  - ...
+  - ...
+  - (share your experience)
+
+- How do you handle collaborative issues e.g. conflicting changes?
+  - ...
+  - ...
+  - (share your experience)
+
+
+
+

Please write or discuss your ideas before opening solution!

+
+ +
+
+
+

Reproducible publications

+
    +

  • Git can be used to collaborate on manuscripts written in, e.g., LaTeX and other text-based formats but other tools exist:

    +
      +

    • Overleaf: an online, collaborative LaTeX editor (has Git integration)

      • +

    • Authorea: collaborative platform for preprints (apparently also has Git integration)

      • +

    • HackMD: an online collaborative Markdown editor (has Git integration)

      • +

    • Manuscripts.io: a collaborative authoring tool that support scientific content and reproducibility.

      • +

    • Google Docs can be a good alternative

      • +
    +
    • +

  • Many tools exist to assist in making scholarly output reproducible:

    +
      +

    • rrtools: instructions, templates, and functions for writing a reproducible article or report with R.

      • +

    • Jupyter Notebooks: web-based computational environment for creating code and text based notebooks that can be used as, see also our Jupyter lesson later in this workshop. +supplementary material for articles.

      • +

    • Binder: makes a repository with Jupyter notebooks available in an executable environment (discussed later in the Jupyter lesson).

      • +

    • “Research compendia”: a set of good practices for +reproducible data analysis in R, but much is transferable to other languages.

Keypoints

+
    +

  • An organized project directory structure helps with reproducibility.

    • +

  • Reproducibility makes work easier for the next person working on the project - and that might be you in a few years!

Questions

+
    +

  • You have some steps that need to be run to do your work. How do you +actually run them? Does it rely on your own memory and work, or is it +reproducible? How do you communicate the steps for future you and others?

    • +

  • How can we create a reproducible workflow?

    • +

  • When to use scientific workflow management systems.

Several steps from input data to result

+

The following material is partly derived from a HPC Carpentry lesson.

+

In this episode, we will use an example +project which finds most frequent +words in books and plots the result from those statistics. In this example we +wish to:

+
    +

  1. Analyze word frequencies using statistics/count.py +for 4 books +(they are all in the data directory).

    2. +

  2. Plot a histogram using plot/plot.py.

    3. +
+
+From book to word counts to plot +
+

Example (for one book only):

+
$ python statistics/count.py data/isles.txt > statistics/isles.data
+$ python plot/plot.py --data-file statistics/isles.data --plot-file plot/isles.png
+
+
+
+

Discussion

+

We have two steps and 4 books. But imagine having 4 steps and processing 500 books. +Can you relate? Are you using similar setups in your research? How do you record them?

+
+
+

Kitchen analogy

+
+Busy kitchen +
+

Now we have many similar meals to prepare and possibly many chefs +present (cores) and workflow tools can help us to plan and document the steps +and run them efficiently. [Midjourney, CC-BY-NC 4.0]

Exercise

+
+

Exercise preparation

+

The exercise (below) and pre-exercise discussion uses a simple +word-count repository +(https://github.com/coderefinery/word-count). We should clone the +repository already to prepare to work on it.

+

You could do the exercise either on your own computer, or the Binder +cloud service:

+

On your own computer:

+
    +

  • Activate the coderefinery conda environment with conda activate coderefinery.

    • +

  • Clone the word-count repository:

    +
    $ git clone https://github.com/coderefinery/word-count.git
+
    +
    +
    • +
+

On Binder: +We can also use the cloud service Binder to make sure +we all have the same computing environment. This is interesting from a +reproducible research point of view and it’s explained further in the Jupyter +lesson how this is even +possible.

+
    +

  • Go to https://github.com/coderefinery/word-count and click on the “launch binder” badge in the README.

    • +

  • Once it get started, you can open a new Terminal from the new menu (top right) and select Terminal.

    • +
+
+
+

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

    • +
+ +
+
+

Workflow-2: Workflow solution using Snakemake

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

    10. +
+ +
+
+
+

Why Snakemake?

+
    +

  • Gentle learning curve.

    • +

  • Free, open-source, and installs easily via conda or pip.

    • +

  • Cross-platform (Windows, MacOS, Linux) and compatible with all HPC schedulers: +same workflow works without modification and scales appropriately whether on a laptop or cluster.

    • +

  • Heavily used in bioinformatics, but is completely general.

    • +

  • Is is possible to define isolated software environments per rule, see here.

    • +

  • Also possible to run workflows in Docker or Apptainer containers.

    • +

  • Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up.

    • +

  • If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel.

    • +

  • Nice functionality for archiving the workflow, see: the official documentation

    • +
+
+
+

Similar tools

+ +
+
+

Visualizing the workflow

+

We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the --dag option, which will output the DAG in dot language.

+

Note: This requires the Graphviz software, +which can be installed by conda install graphviz. It’s not necessary to +run this step yourself.

+
$ snakemake -j 1 --dag | dot -Tpng > dag.png
+
+
+

Rules that have yet to be completed are indicated with solid outlines, while already completed rules are indicated with dashed outlines.

Tools and what problems they try to solve

+

Conda, Anaconda, pip, virtualenv, Pipenv, pyenv, Poetry, requirements.txt, +environment.yml, renv, …, these tools try to solve the following problems:

+
    +

  • Defining a specific set of dependencies, possibly with well defined versions

    • +

  • Installing those dependencies mostly automatically

    • +

  • Recording the versions for all dependencies

    • +

  • Isolate environments

    +
      +

    • On your computer for projects so they can use different software

      • +

    • Isolate environments on computers with many users (and allow self-installations)

      • +
    +
    • +

  • Using different Python/R versions per project

    • +

  • Provide tools and services to share packages

    • +
+

Isolated environments are also useful because they help you make sure +that you know your dependencies!

+

If things go wrong, you can delete and re-create - much better +than debugging. The more often you re-create your environment, the +more reproducible it is.

+

Exercises

+
+

Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+

Answer in the collaborative document:

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click
+  - python
+  - pip
+  - pip:
+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +
    name: student-project
+channels:

+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4

Dependencies-2: Create a time-capsule for the future

+

Now we will demo creating our own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+
+

What is a container?

+

Imagine if you didn’t have to install things yourself, but instead you could +get a computer with the exact software for a task pre-installed? Containers +effectively do that, with various advantages and disadvantages. They are +like an entire operating system with software installed, all in one file,

+
+He said, then we will ship your machine. And that's how Docker was born. +

Kitchen analogy

    • +

  • Container definition files <-> like a blueprint to build a kitchen with all +utensils in which the recipe can be prepared.

    • +

  • Container images <-> example kitchens

+
+

From definition files to container images to containers

+
    +

  • Containers can be built to bundle all the necessary ingredients (data, code, environment, operating system).

    • +

  • A container image is like a piece of paper with all the operating system on it. When you run it, +a transparent sheet is placed on top to form a container. The container runs and writes only on +that transparent sheet (and what other mounts have been layered on top). When you are done, +transparency is thrown away. It can be repeated as often as you want, and base is always the same.

    • +

  • Definition files (e.g. Dockerfile or Singularity definition file) are text +files that contain a series of instructions to build container images.

    • +
+
+
+

You may have use for containers in different ways

+
    +

  • Installing a certain software is tricky, or not supported for your operating system? -> See if an image is available and run the software from a container instead!

    • +

  • You want to make sure your colleagues are using the same environment for running your code? -> Provide them an image of your container!

    +
      +

    • If this does not work, because they are using a different architecture than you do? -> Provide a definition file for them to build the image suitable to their computers. This does not create the exact environment as you have, but in most cases similar enough.

      • +
    +
    • +
+
+
+

The container recipe

+

Here is an example of a Singularity definition file (reference):

+
Bootstrap: docker
+From: ubuntu:20.04
+
+%post
+    apt-get -y update
+    apt-get -y install cowsay lolcat
+
+%environment
+    export LC_ALL=C
+    export PATH=/usr/games:$PATH
+
+%runscript
+    date | cowsay | lolcat
+
+
+

Popular container implementations:

+ +

They are to some extent interoperable:

+
    +

  • podman is very close to Docker

    • +

  • Docker images can be converted to Singularity/Apptainer images

    • +

  • Singularity Python can convert Dockerfiles to Singularity definition files

    • +
+
+
+
+

Pros and cons of containers

+

Containers are popular for a reason - they solve a number of +important problems:

+
    +

  • Allow for seamlessly moving workflows across different platforms.

    • +

  • Can solve the “works on my machine” situation.

    • +

  • For software with many dependencies, in turn with its own dependencies, +containers offer possibly the only way to preserve the +computational experiment for future reproducibility.

    • +

  • A mechanism to “send the computer to the data” when data is too

    • +

  • Installing software into a file instead of into your computer (removing +a file is often easier than uninstalling software if you suddenly regret an +installation)

    • +
+

However, containers may also have some drawbacks:

+
    +

  • Can be used to hide away software installation problems and thereby +discourage good software development practices.

    • +

  • Instead of “works on my machine” problem: “works only in this container” problem?

    • +

  • They can be difficult to modify (this is the focus of an exercise below)

    • +

  • Container images can become large

    • +
+
+

Danger

+

Use only official and trusted images! Not all images can be trusted! There +have been examples of contaminated images so investigate before using images +blindly. Apply same caution as installing software packages from untrusted +package repositories.

+
+
+
+
+

Where can one share or find images?

+ +
+
+
+

Exercises

+
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

(optional) Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash
+

Objectives

+
    +

  • Understand when tools discussed in this episode can be useful

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching/discussion

    • +
+
+

This episode presents a lot of different tools and opportunities for your research software project. +However, you will not always need all of them. As with so many things, it again depends on your project.

+
+

Important for every project

+
    +

  • Clear file structure for your project

    • +

  • At least consider the possibility that someone, maybe you may want to reproduce your work

    +
      +

    • Can you do something (small) to make it easier?

      • +

    • If you have ideas, but no time: add an issue to your repository; maybe someone else wants to help.

      • +
    +
    • +
+
+
+

Workflow tools will maybe make sense in the future

+
    +

  • In many cases, it is probably not needed

    • +

  • You will want to consider workflow tools:

    +
      +

    • When processing many files with many steps

      • +

    • Steps or files may change

      • +

    • Your main script, connecting your steps gets very long

      • +

    • …

      • +
    +
    • +
+
+
+

When should I worry about dependencies?

+
    +

  • Your code depends on multiple other packages

    • +

  • You want to avoid questions like: “What do I need to install to run your code”

    • +

  • You want help yourself running your code

    +
      +

    • After a few years

      • +

    • On a different computer

      • +

    • …

      • +
    +
    • +
+
+
+

Containers seem amazing, but do I have use for them?

+
    +

  • Maybe not yet, but knowing that you can …

    +
      +

    • Run Linux tools on your Windows computer

      • +

    • Run different versions of same software on your computer

      • +

    • Follow the “easy installation instructions” for an operating system that is not your own

      • +

    • Get a fully configured environment instead of only installing a tool

      • +

    • Share your setup and configurations with others +… can be very beneficial :)

Detailed day schedule

+

Two example schedules for this lesson:

+

This is the planned schedule for the workshop in September 2023 (2 hours and 5 minutes including 10 min break) ; note that for this workshop, sharing code and data was moved to social coding lesson:

+ +

This was the schedule at workshop in March 2023 (2 hours and 15 minutes including 2x 10 min break):

+ +
+
+

Why we teach this lesson

+

Reproducibility in research is something that publishers, funding agencies, universities, +research leaders and the general public worries about and much is being written about it. +It is also something that researchers care deeply about - this lesson is typically one of the +most popular lessons in the pre-workshop survey.

+

Even though most PhD students, postdocs and researchers (i.e. typical workshop participants) +know about the importance of reproducibility in research, they often lack both a general +overview of what different aspects there are to reproducibility, and the knowledge of +specific tools that can be used for improving reproducibility.

+

Many participants may not adhere to good practices when organizing their projects, +and the “Organizing your projects” episode is meant to encourage participants to +structure their projects better. This may be obvious to some participants but it +doesn’t harm to preach to the choir.

+

Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people’s code to run), they +often don’t know or use good practices when it comes to recording dependencies. +Most participants also don’t use isolated environments for different projects and +don’t know why that can be important. +The episode “Recording dependencies” tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager.

+

Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +“Recording environments” introduces the concept of containers, and the optional +episode “Creating and sharing a container image” goes into details.

+

Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of “scientific workflows”, +and that there actually exist tools that help make such workflows reproducible. +The episode “Recording computational steps” introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible.

+
+
+

How to teach this lesson

+
+

How to start

+

Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we’re going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers).

+
+
+

Focus on concepts, and when to use which tool

+

Try to explain better what the different tools are useful for, but don’t go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem.

+
+
+
+

Typical pitfalls

+
+

Indentation in Snakefiles

+
    +

  • the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn’t matter +This works:

    • +
+
rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+
+

but this doesn’t work:

+
rule all:
+    input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+

nor this:

+
rule all:
+input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+
+
+
+

Field reports

+
+

2022 September

+

We used the strategy “absolutely minimal introductions, most time +for exercise”. Overall, it was probably the right thing to do since +there is so little time and so much to cover.

+

There wasn’t enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode.

+

The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn’t really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day.

Objectives

+
    +

  • Understand when tools discussed in this episode can be useful

    • +
+

Instructor note

+
    +

  • 10 min teaching/discussion

    • +
+
+

This episode presents a lot of different tools and opportunities for your research software project. +However, you will not always need all of them. As with so many things, it again depends on your project.

+
+

Important for every project

+
    +

  • Clear file structure for your project

    • +

  • At least consider the possibility that someone, maybe you may want to reproduce your work

    +
      +

    • Can you do something (small) to make it easier?

      • +

    • If you have ideas, but no time: add an issue to your repository; maybe someone else wants to help.

      • +
    +
    • +
+
+
+

Workflow tools will maybe make sense in the future

+
    +

  • In many cases, it is probably not needed

    • +

  • You will want to consider workflow tools:

    +
      +

    • When processing many files with many steps

      • +

    • Steps or files may change

      • +

    • Your main script, connecting your steps gets very long

      • +

    • …

      • +
    +
    • +
+
+
+

When should I worry about dependencies?

+
    +

  • Your code depends on multiple other packages

    • +

  • You want to avoid questions like: “What do I need to install to run your code”

    • +

  • You want help yourself running your code

    +
      +

    • After a few years

      • +

    • On a different computer

      • +

    • …

      • +
    +
    • +
+
+
+

Containers seem amazing, but do I have use for them?

+
    +

  • Maybe not yet, but knowing that you can …

    +
      +

    • Run Linux tools on your Windows computer

      • +

    • Run different versions of same software on your computer

      • +

    • Follow the “easy installation instructions” for an operating system that is not your own

      • +

    • Get a fully configured environment instead of only installing a tool

      • +

    • Share your setup and configurations with others +… can be very beneficial :)

Recording computational steps

+
+

Questions

+
    +

  • You have some steps that need to be run to do your work. How do you +actually run them? Does it rely on your own memory and work, or is it +reproducible? How do you communicate the steps for future you and others?

    • +

  • How can we create a reproducible workflow?

    • +

  • When to use scientific workflow management systems.

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching

    • +

  • 20 min exercises

    • +
+
+
+

Several steps from input data to result

+

The following material is partly derived from a HPC Carpentry lesson.

+

In this episode, we will use an example +project which finds most frequent +words in books and plots the result from those statistics. In this example we +wish to:

+
    +

  1. Analyze word frequencies using statistics/count.py +for 4 books +(they are all in the data directory).

    2. +

  2. Plot a histogram using plot/plot.py.

    3. +
+
+From book to word counts to plot +
+

Example (for one book only):

+
$ python statistics/count.py data/isles.txt > statistics/isles.data
+$ python plot/plot.py --data-file statistics/isles.data --plot-file plot/isles.png
+
+
+
+

Discussion

+

We have two steps and 4 books. But imagine having 4 steps and processing 500 books. +Can you relate? Are you using similar setups in your research? How do you record them?

+
+
+

Kitchen analogy

+
+Busy kitchen +
+

Now we have many similar meals to prepare and possibly many chefs +present (cores) and workflow tools can help us to plan and document the steps +and run them efficiently. [Midjourney, CC-BY-NC 4.0]

+
+

Exercise

+
+

Exercise preparation

+

The exercise (below) and pre-exercise discussion uses a simple +word-count repository +(https://github.com/coderefinery/word-count). We should clone the +repository already to prepare to work on it.

+

You could do the exercise either on your own computer, or the Binder +cloud service:

+

On your own computer:

+
    +

  • Activate the coderefinery conda environment with conda activate coderefinery.

    • +

  • Clone the word-count repository:

    +
    $ git clone https://github.com/coderefinery/word-count.git
+
    +
    +
    • +
+

On Binder: +We can also use the cloud service Binder to make sure +we all have the same computing environment. This is interesting from a +reproducible research point of view and it’s explained further in the Jupyter +lesson how this is even +possible.

+
    +

  • Go to https://github.com/coderefinery/word-count and click on the “launch binder” badge in the README.

    • +

  • Once it get started, you can open a new Terminal from the new menu (top right) and select Terminal.

    • +
+
+
+

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

    • +
+ +
+
+

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

    10. +
+ +
+
+
+

Why Snakemake?

+
    +

  • Gentle learning curve.

    • +

  • Free, open-source, and installs easily via conda or pip.

    • +

  • Cross-platform (Windows, MacOS, Linux) and compatible with all HPC schedulers: +same workflow works without modification and scales appropriately whether on a laptop or cluster.

    • +

  • Heavily used in bioinformatics, but is completely general.

    • +

  • Is is possible to define isolated software environments per rule, see here.

    • +

  • Also possible to run workflows in Docker or Apptainer containers.

    • +

  • Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up.

    • +

  • If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel.

    • +

  • Nice functionality for archiving the workflow, see: the official documentation

    • +
+
+
+

+ +
+
+

Visualizing the workflow

+

We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the --dag option, which will output the DAG in dot language.

+

Note: This requires the Graphviz software, +which can be installed by conda install graphviz. It’s not necessary to +run this step yourself.

+
$ snakemake -j 1 --dag | dot -Tpng > dag.png
+
+
+

Rules that have yet to be completed are indicated with solid outlines, while already completed rules are indicated with dashed outlines.

This may be obvious to some participants but it +doesn't harm to preach to the choir. + +Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people's code to run), they +often don't know or use good practices when it comes to recording dependencies. +Most participants also don't use isolated environments for different projects and +don't know why that can be important. +The episode "Recording dependencies" tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager. + +Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +"Recording environments" introduces the concept of containers, and the optional +episode "Creating and sharing a container image" goes into details. + +Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of "scientific workflows", +and that there actually exist tools that help make such workflows reproducible. +The episode "Recording computational steps" introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible. + + +## How to teach this lesson + +### How to start + +Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this.

In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem. + + +## Typical pitfalls + +### Indentation in Snakefiles + +- the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn't matter +This works: +```python +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` +but this doesn't work: +```python +rule all: + input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` +nor this: +```python +rule all: +input: + expand('statistics/{book}.data', book=DATA), + expand('plot/{book}.png', book=DATA) +``` + + +## Field reports + +### 2022 September + +We used the strategy "absolutely minimal introductions, most time +for exercise".

We currently have two steps and 4 books. But **imagine having 4 steps and 500 books**. +How could we deal with this? + +As a first idea we could express the workflow with a script. The repository includes such script called `run_all.sh`. +We can run it with: +```console +$ bash run_all.sh +``` + +This is **imperative style**: we tell the script to run these +steps in precisely this order, as we would run them manually, one after another. + +````{discussion} +- What are the advantages of this solution compared to processing all one by one? +- Is the scripted solution reproducible? +- Imagine adding more steps to the analysis and imagine the steps being time consuming.

But could you easily run it e.g. on a Windows computer? + + If we had more steps and once steps start to be time-consuming, a limitation of + a scripted solution is that it tries to run all steps always.

Clone the example to your computer: `$ git clone https://github.com/coderefinery/word-count.git` +2. Study the Snakefile. How does it know what to do first and what to do then? +3. Try to run it. Since version 5.11 one needs to specify number of cores (or + jobs) using `-j`, `--jobs` or `--cores`: + ```console + $ snakemake --delete-all-output -j 1 + $ snakemake -j 1 + ``` + The `--delete-all-output` part makes sure that we remove all generated files before we start. +4. Try running `snakemake` again and observe that and discuss why it refused to rerun all steps: + ```console + $ snakemake -j 1 + + Building DAG of jobs... + Nothing to be done (all requested files are present and up to date). + ``` +5. Make a tiny modification to the plot.py script and run `$ snakemake -j 1` again and observe how it will only re-run the plot steps. +6. Make a tiny modification to one of the books and run `$ snakemake -j 1` again and observe how it only regenerates files for this book. +7. Discuss possible advantages compared to a scripted solution. +8. **Question for R developers**: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in + the [Snakefile](https://github.com/coderefinery/word-count/blob/main/Snakefile) would you have to modify so that it uses your R code? +9. If you make changes to the Snakefile, validate it using `$ snakemake --lint`. + +```{solution} +- 2: Start with "all" and look what it depends on. Now search for rules that + have these as output. Look for their inputs and search where they + are produced. In other words, search backwards and build a graph of + dependencies. This is what Snakemake does. +- 4: It can see that outputs are newer than inputs. It will only regenerate + outputs if they are not there or if the inputs or scripts have changed. +- 7: It only generates steps and outputs that are missing or outdated. The workflow + does not run everything every time. In other words if you notice a problem or update information + "half way" in the analysis, it will only re-run what needs to be re-run. Nothing more, nothing less. + Another advantage is that it can distribute tasks to multiple cores, off-load work to supercomputers, + offers more fine-grained control over environments, and more. +- 8: Probably only the two lines containing "shell". +``` +```` +## Visualizing the workflow + +We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the `--dag` option, which will output the DAG in `dot` language. + +**Note**: This requires the [Graphviz software](https://www.graphviz.org/), +which can be installed by `conda install graphviz`. + +```console +$ snakemake -j 1 --dag | dot -Tpng > dag.png +``` +Rules that have yet to be completed are indicated with solid outlines, while already completed rules are indicated with dashed outlines. + +```{figure} img/snakemake_dag.png +:alt: Snakemake DAG +:width: 100% +``` + +## Why [Snakemake](https://snakemake.readthedocs.io/)? + +- Gentle learning curve. +- Free, open-source, and installs easily via conda or pip. +- Cross-platform (Windows, MacOS, Linux) and compatible with all High Performance Computing (HPC) schedulers: + same workflow works without modification and scales appropriately whether on a laptop or cluster. +- [Heavily used in bioinformatics](https://twitter.com/carl_witt/status/1103951128046301185), but is **completely general**. +- Is is possible to define isolated software environments per rule, see [here](https://github.com/coderefinery/word-count/blob/f4ca47440751dd2c65f55fef1a8d9f181ecdd2f6/Snakefile#L15). +- Also possible to run workflows in Docker or Apptainer containers. +- Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up. +- If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel. +- Nice functionality for archiving the workflow, see: [the official documentation](https://snakemake.readthedocs.io/en/stable/snakefiles/deployment.html#sustainable-and-reproducible-archiving) + +Tools like Snakemake help us with **reproducibility** by supporting us with **automation**, **scalability** and **portability** of our workflows. + + +## Similar tools + +- [Make](https://www.gnu.org/software/make/) +- [Nextflow](https://www.nextflow.io/) +- [Task](https://taskfile.dev/) +- [Common Workflow Language](https://www.commonwl.org/) +- Many [specialized frameworks](https://github.com/common-workflow-language/common-workflow-language/wiki/Existing-Workflow-systems) exist. +- [Book on building reproducible analytical pipelines with R](https://raps-with-r.dev/) + + + diff --git a/branch/swi_snakemake/_static/_sphinx_javascript_frameworks_compat.js b/branch/swi_snakemake/_static/_sphinx_javascript_frameworks_compat.js new file mode 100644 index 0000000..8141580 --- /dev/null +++ b/branch/swi_snakemake/_static/_sphinx_javascript_frameworks_compat.js @@ -0,0 +1,123 @@ +/* Compatability shim for jQuery and underscores.js. + * + * Copyright Sphinx contributors + * Released under the two clause BSD licence + */ + +/** + * small helper function to urldecode strings + * + * See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/decodeURIComponent#Decoding_query_parameters_from_a_URL + */ +jQuery.urldecode = function(x) { + if (!x) { + return x + } + return decodeURIComponent(x.replace(/\+/g, ' ')); +}; + +/** + * small helper function to urlencode strings + */ +jQuery.urlencode = encodeURIComponent; + +/** + * This function returns the parsed url parameters of the + * current request.

    +

  • Reproducibility: We can version-control our code with Git but how should we version-control dependencies? +How can we capture and communicate dependencies?

    • +

  • Dependency hell: Different codes on the same environment can have conflicting dependencies.

Tools and what problems they try to solve

+

Conda, Anaconda, pip, virtualenv, Pipenv, pyenv, Poetry, requirements.txt, +environment.yml, renv, …, these tools try to solve the following problems:

+
    +

  • Defining a specific set of dependencies, possibly with well defined versions

    • +

  • Installing those dependencies mostly automatically

    • +

  • Recording the versions for all dependencies

    • +

  • Isolate environments

    +
      +

    • On your computer for projects so they can use different software

      • +

    • Isolate environments on computers with many users (and allow self-installations)

      • +
    +
    • +

  • Using different Python/R versions per project

    • +

  • Provide tools and services to share packages

    • +
+

Isolated environments are also useful because they help you make sure +that you know your dependencies!

+

If things go wrong, you can delete and re-create - much better +than debugging. The more often you re-create your environment, the +more reproducible it is.

Exercises

+

(optional) Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+

Answer in the collaborative document:

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click
+  - python
+  - pip
+  - pip:
+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4
+  - sympy=1.4
+  - click=7.0
+  - python=3.8
+  - pip
+  - pip:
+    - git+https://github.com/someuser/someproject.git@d7b2c7e
+    - git+https://github.com/anotheruser/anotherproject.git@sometag
+
    +
    +

    E: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4

+  - anotherproject=2.3.4
+
    +
    +
    + +
    • +
+
+
+

(optional) Dependencies-2: Create a time-capsule for the future

+

Now it is time to create your own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+
+
+

What is a container?

+

Imagine if you didn’t have to install things yourself, but instead you could +get a computer with the exact software for a task pre-installed? Containers +effectively do that, with various advantages and disadvantages. They are +like an entire operating system with software installed, all in one file,

+
+He said, then we will ship your machine. And that's how Docker was born. +

From definition files to container images to containers

+
    +

  • Containers can be built to bundle all the necessary ingredients (data, code, environment, operating system).

    • +

  • A container image is like a piece of paper with all the operating system on it. When you run it, +a transparent sheet is placed on top to form a container. The container runs and writes only on +that transparent sheet (and what other mounts have been layered on top). When you are done, +transparency is thrown away. It can be repeated as often as you want, and base is always the same.

    • +

  • Definition files (e.g. Dockerfile or Singularity definition file) are text +files that contain a series of instructions to build container images.

    • +
+
+
+

You may have use for containers in different ways

+
    +

  • Installing a certain software is tricky, or not supported for your operating system? -> See if an image is available and run the software from a container instead!

    • +

  • You want to make sure your colleagues are using the same environment for running your code? -> Provide them an image of your container!

    +
      +

    • If this does not work, because they are using a different architecture than you do? -> Provide a definition file for them to build the image suitable to their computers. This does not create the exact environment as you have, but in most cases similar enough.

      • +
    +
    • +
+
+
+

The container recipe

+

Here is an example of a Singularity definition file (reference):

+
Bootstrap: docker
+From: ubuntu:20.04
+
+%post
+    apt-get -y update
+    apt-get -y install cowsay lolcat
+
+%environment
+    export LC_ALL=C
+    export PATH=/usr/games:$PATH
+
+%runscript
+    date | cowsay | lolcat
+
+
+

Popular container implementations:

+ +

They are to some extent interoperable:

+
    +

  • podman is very close to Docker

    • +

  • Docker images can be converted to Singularity/Apptainer images

    • +

  • Singularity Python can convert Dockerfiles to Singularity definition files

    • +
+
+
+
+

Pros and cons of containers

+

Containers are popular for a reason - they solve a number of +important problems:

+
    +

  • Allow for seamlessly moving workflows across different platforms.

    • +

  • Can solve the “works on my machine” situation.

    • +

  • For software with many dependencies, in turn with its own dependencies, +containers offer possibly the only way to preserve the +computational experiment for future reproducibility.

    • +

  • A mechanism to “send the computer to the data” when data is too

    • +

  • Installing software into a file instead of into your computer (removing +a file is often easier than uninstalling software if you suddenly regret an +installation)

    • +
+

However, containers may also have some drawbacks:

+
    +

  • Can be used to hide away software installation problems and thereby +discourage good software development practices.

    • +

  • Instead of “works on my machine” problem: “works only in this container” problem?

    • +

  • They can be difficult to modify (this is the focus of an exercise below)

    • +

  • Container images can become large

    • +
+
+

Danger

+

Use only official and trusted images! Not all images can be trusted! There +have been examples of contaminated images so investigate before using images +blindly. Apply same caution as installing software packages from untrusted +package repositories.

+
+
+
+
+

Where can one share or find images?

+ +
+
+
+

Exercises

+
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

(optional) Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash
+
    +

Workflow-1: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution in the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

We can see that Snakemake uses declarative style: +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Steps:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

In dependencies.md:

+
+

(optional) Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+

Answer in the collaborative document:

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click
+  - python
+  - pip
+  - pip:
+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4
+  - sympy=1.4
+  - click=7.0
+  - python=3.8
+  - pip
+  - pip:
+    - git+https://github.com/someuser/someproject.git@d7b2c7e
+    - git+https://github.com/anotheruser/anotherproject.git@sometag
+
    +
    +

    E: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4

(optional) Dependencies-2: Create a time-capsule for the future

+

Now it is time to create your own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

Detailed day schedule

+

Two example schedules for this lesson:

+

This is the planned schedule for the workshop in September 2023 (2 hours and 5 minutes including 10 min break) ; note that for this workshop, sharing code and data was moved to social coding lesson:

+ +

This was the schedule at workshop in March 2023 (2 hours and 15 minutes including 2x 10 min break):

+ +
+
+

Why we teach this lesson

+

Reproducibility in research is something that publishers, funding agencies, universities, +research leaders and the general public worries about and much is being written about it. +It is also something that researchers care deeply about - this lesson is typically one of the +most popular lessons in the pre-workshop survey.

+

Even though most PhD students, postdocs and researchers (i.e. typical workshop participants) +know about the importance of reproducibility in research, they often lack both a general +overview of what different aspects there are to reproducibility, and the knowledge of +specific tools that can be used for improving reproducibility.

+

Many participants may not adhere to good practices when organizing their projects, +and the “Organizing your projects” episode is meant to encourage participants to +structure their projects better. This may be obvious to some participants but it +doesn’t harm to preach to the choir.

+

Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people’s code to run), they +often don’t know or use good practices when it comes to recording dependencies. +Most participants also don’t use isolated environments for different projects and +don’t know why that can be important. +The episode “Recording dependencies” tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager.

+

Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +“Recording environments” introduces the concept of containers, and the optional +episode “Creating and sharing a container image” goes into details.

+

Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of “scientific workflows”, +and that there actually exist tools that help make such workflows reproducible. +The episode “Recording computational steps” introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible.

+
+
+

How to teach this lesson

+
+

How to start

+

Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we’re going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers).

+
+
+

Focus on concepts, and when to use which tool

+

Try to explain better what the different tools are useful for, but don’t go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem.

+
+
+
+

Typical pitfalls

+
+

Indentation in Snakefiles

+
    +

  • the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn’t matter +This works:

    • +
+
rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+
+

but this doesn’t work:

+
rule all:
+    input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+

nor this:

+
rule all:
+input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+
+
+
+

Field reports

+
+

2022 September

+

We used the strategy “absolutely minimal introductions, most time +for exercise”. Overall, it was probably the right thing to do since +there is so little time and so much to cover.

+

There wasn’t enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode.

+

The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn’t really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day.

Reproducible research - Preparing code to be usable by you and others in the future

+

Have you ever spent days trying to repeat the results from few weeks or months +ago? Or you have to do paper revisions, but you just can’t get the results to +match up? It’s unpleasant for both you and science.

+

In this lesson we will explore different methods and tools for better +reproducibility in research software and data. We will demonstrate how version +control, workflows, containers, and package managers can be used to record +reproducible environments and computational steps for our future selves.

+
+

A scary anecdote

+
    +

  • A group of researchers obtain great results and submit their work to a high-profile journal.

    • +

  • Reviewers ask for new figures and additional analysis.

    • +

  • The researchers start working on revisions and generate modified figures, but find inconsistencies with old figures.

    • +

  • The researchers can’t find some of the data they used to generate the original results, and +can’t figure out which parameters they used when running their analyses.

    • +

  • The manuscript is still languishing in the drawer …

    • +
+
+
+
+

Why talking about reproducible research?

+

A 2016 +survey +in Nature revealed that irreproducible experiments are a problem across all +domains of science:

+
+reproduciblity Nature +
+

This study is now few years old but the highlighted problem did not get +smaller.

+
+
+
+

Levels of reproducibility

+

A published article is like the top of a pyramid. It rests on multiple +levels that each contributes to its reproducibility.

+
+Reproducibility pyramid +

Organizing your projects

+
+

Objectives

+
    +

  • Get an overview on how to organize research projects

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching incl. discussions

    • +
+
+

One of the most basic steps to make your work reproducible is to organize your projects well. +Let’s go over some of the basic things which people have found to work (and not to work).

+
+

Directory structure for projects

+
    +

  • Project files in a single folder

    • +

  • Different projects should have separate folders

    • +

  • Use consistent and informative directory structure

    +
      +

    • Avoid spaces in directory and file names – it is uglier for humans but handy for computers.

      • +
    +
    • +

  • If you need to separate public/private, you can put them in public and private Git repos

    +
      +

    • If you need to separate public/secret, use .gitignore or a separate folder that’s not in Git

      • +
    +
    • +

  • Add a README file to describe the project and instructions on reproducing the results

    • +

  • If a software is reused in several projects it can make sense to put them in own repo

    • +
+

A project directory can look something like this:

+
project_name/
+├── README.md             # overview of the project
+├── data/                 # data files used in the project
+│   ├── README.md         # describes where data came from
+│   └── sub-folder/       # may contain subdirectories
+├── processed_data/       # intermediate files from the analysis
+├── manuscript/           # manuscript describing the results
+├── results/              # results of the analysis (data, tables, figures)
+├── src/                  # contains all code in the project
+│   ├── LICENSE           # license for your code
+│   ├── requirements.txt  # software requirements and dependencies
+│   └── ...
+└── doc/                  # documentation for your project
+    ├── index.rst
+    └── ...
+
+
+
+
+
+

Tracking source code, data, and results

+
    +

  • All code is version controlled and goes in the src/ or source/ directory

    • +

  • Include appropriate LICENSE file and information on software requirements

    • +

  • You can also version control data files or input files under data/

    • +

  • If data files are too large (or sensitive) to track, untrack them using .gitignore

    • +

  • Intermediate files from the analysis are kept in processed_data/

    • +

  • Consider using Git tags to mark specific versions of results (version +submitted to a journal, dissertation version, poster version, etc.):

    +
    $ git tag -a thesis-submitted -m "this is the submitted version of my thesis"
+
    +
    +
    • +
+ +
+
+
+

Reproducible publications

+
    +

  • Git can be used to collaborate on manuscripts written in, e.g., LaTeX and other text-based formats but other tools exist:

    +
      +

    • Overleaf: an online, collaborative LaTeX editor (has Git integration)

      • +

    • Authorea: collaborative platform for preprints (apparently also has Git integration)

      • +

    • HackMD: an online collaborative Markdown editor (has Git integration)

      • +

    • Manuscripts.io: a collaborative authoring tool that support scientific content and reproducibility.

      • +

    • Google Docs can be a good alternative

      • +
    +
    • +

  • Many tools exist to assist in making scholarly output reproducible:

    +
      +

    • rrtools: instructions, templates, and functions for writing a reproducible article or report with R.

      • +

    • Jupyter Notebooks: web-based computational environment for creating code and text based notebooks that can be used as, see also our Jupyter lesson later in this workshop. +supplementary material for articles.

      • +

    • Binder: makes a repository with Jupyter notebooks available in an executable environment (discussed later in the Jupyter lesson).

      • +

    • “Research compendia”: a set of good practices for +reproducible data analysis in R, but much is transferable to other languages.

      • +

Discussion on reproducibility

+
+

Discuss in collaborative document or with your team members

+

How do you collaborate on writing academic papers?

+
- Are you using version control for academic papers?
+  - ...
+  - ...
+  - (share your experience)
+
+- How do you handle collaborative issues e.g. conflicting changes?
+  - ...
+  - ...
+  - (share your experience)
+
+
+
+

Please write or discuss your ideas before opening solution!

+
+ +
+
+

Discuss in collaborative document or with your team members

+
- What tools are you using when organizing your projects?
+  - ...
+  - ...
+  - (share your experience)
+
+
+
+
+

Keypoints

+
    +

  • An organized project directory structure helps with reproducibility.

    • +

  • Reproducibility makes work easier for the next person working on the project - and that might be you in a few years!

Reproducible research - Preparing code to be usable by you and others in the future

+

Have you ever spent days trying to repeat the results from few weeks or months +ago? Or you have to do paper revisions, but you just can’t get the results to +match up? It’s unpleasant for both you and science.

+

In this lesson we will explore different methods and tools for better +reproducibility in research software and data. We will demonstrate how version +control, workflows, containers, and package managers can be used to record +reproducible environments and computational steps for our future selves.

+
+

    • +

  • remember the FAIR principles

    • +

  • understand that code can have dependencies, and know how to document them

    • +

  • if a computational studies contains several steps, be able to document them

    • +

  • know about use cases for containers

    • +

  • knowing the pros and cons of manual documentation vs. scripted automation vs. workflow management

A scary anecdote

+
    +

  • A group of researchers obtain great results and submit their work to a high-profile journal.

    • +

  • Reviewers ask for new figures and additional analysis.

    • +

  • The researchers start working on revisions and generate modified figures, but find inconsistencies with old figures.

    • +

  • The researchers can’t find some of the data they used to generate the original results, and +can’t figure out which parameters they used when running their analyses.

    • +

  • The manuscript is still languishing in the drawer …

    • +
+
+
+
+

Why talking about reproducible research?

+

A 2016 +survey +in Nature revealed that irreproducible experiments are a problem across all +domains of science:

+
+reproduciblity Nature +
+

This study is now few years old but the highlighted problem did not get +smaller.

+
+
+
+

Levels of reproducibility

+

A published article is like the top of a pyramid. It rests on multiple +levels that each contributes to its reproducibility.

+
+Reproducibility pyramid +

+

This also means that you can think about it from the beginning of your research life cycle!

+  - (share your experience)
+
+- Have you continued working from a previous student's

Organizing your projects

+
+

Objectives

+
    +

  • Get an overview on how to organize research projects

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching incl. discussions

    • +
+
+

One of the most basic steps to make your work reproducible is to organize your projects well. +Let’s go over some of the basic things which people have found to work (and not to work).

+
+

Directory structure for projects

+
    +

  • Project files in a single folder

    • +

  • Different projects should have separate folders

    • +

  • Use consistent and informative directory structure

    +
      +

    • Avoid spaces in directory and file names – it is uglier for humans but handy for computers.

      • +
    +
    • +

  • If you need to separate public/private, you can put them in public and private Git repos

    +
      +

    • If you need to separate public/secret, use .gitignore or a separate folder that’s not in Git

      • +
    +
    • +

  • Add a README file to describe the project and instructions on reproducing the results

    • +

  • If a software is reused in several projects it can make sense to put them in own repo

    • +
+

A project directory can look something like this:

+
project_name/
+├── README.md             # overview of the project
+├── data/                 # data files used in the project
+│   ├── README.md         # describes where data came from
+│   └── sub-folder/       # may contain subdirectories
+├── processed_data/       # intermediate files from the analysis
+├── manuscript/           # manuscript describing the results
+├── results/              # results of the analysis (data, tables, figures)
+├── src/                  # contains all code in the project
+│   ├── LICENSE           # license for your code
+│   ├── requirements.txt  # software requirements and dependencies
+│   └── ...
+└── doc/                  # documentation for your project
+    ├── index.rst
+    └── ...
+
+
+
+
+
+

Tracking source code, data, and results

+
    +

  • All code is version controlled and goes in the src/ or source/ directory

    • +

  • Include appropriate LICENSE file and information on software requirements

    • +

  • You can also version control data files or input files under data/

    • +

  • If data files are too large (or sensitive) to track, untrack them using .gitignore

    • +

  • Intermediate files from the analysis are kept in processed_data/

    • +

  • Consider using Git tags to mark specific versions of results (version +submitted to a journal, dissertation version, poster version, etc.):

    +
    $ git tag -a thesis-submitted -m "this is the submitted version of my thesis"
+
    +
    +
    • +
+ +
+
+
+

Reproducible publications

+
    +

  • Git can be used to collaborate on manuscripts written in, e.g., LaTeX and other text-based formats but other tools exist:

    +
      +

    • Overleaf: an online, collaborative LaTeX editor (has Git integration)

      • +

    • Authorea: collaborative platform for preprints (apparently also has Git integration)

      • +

    • HackMD: an online collaborative Markdown editor (has Git integration)

      • +

    • Manuscripts.io: a collaborative authoring tool that support scientific content and reproducibility.

      • +

    • Google Docs can be a good alternative

      • +
    +
    • +

  • Many tools exist to assist in making scholarly output reproducible:

    +
      +

    • rrtools: instructions, templates, and functions for writing a reproducible article or report with R.

      • +

    • Jupyter Notebooks: web-based computational environment for creating code and text based notebooks that can be used as, see also our Jupyter lesson later in this workshop. +supplementary material for articles.

      • +

    • Binder: makes a repository with Jupyter notebooks available in an executable environment (discussed later in the Jupyter lesson).

      • +

    • “Research compendia”: a set of good practices for +reproducible data analysis in R, but much is transferable to other languages.

Keypoints

+
    +

  • An organized project directory structure helps with reproducibility.

Recording computational steps

+
+

Questions

+
    +

  • You have some steps that need to be run to do your work. How do you +actually run them? Does it rely on your own memory and work, or is it +reproducible? How do you communicate the steps for future you and others?

    • +

  • How can we create a reproducible workflow?

    • +

  • When to use scientific workflow management systems.

Several steps from input data to result

+

The following material is partly derived from a HPC Carpentry lesson.

+

In this episode, we will use an example +project which finds most frequent +words in books and plots the result from those statistics. In this example we +wish to:

+
    +

  1. Analyze word frequencies using statistics/count.py +for 4 books +(they are all in the data directory).

    2. +

  2. Plot a histogram using plot/plot.py.

    3. +
+
+From book to word counts to plot +
+

Example (for one book only):

+
$ python statistics/count.py data/isles.txt > statistics/isles.data
+$ python plot/plot.py --data-file statistics/isles.data --plot-file plot/isles.png
+
+
+

Another way to analyze the data would be via a graphical user interface (GUI), where you can for example drag and drop files and click buttons to do the different processing steps.

+

Both of the above (single line commands and GUIs) are tricky in terms of reproducibility. We currently have two steps and 4 books. But imagine having 4 steps and 500 books. +How could we deal with this?

+

As a first idea we could express the workflow with a script. The repository includes such script called run_all.sh. +We can run it with:

+
$ bash run_all.sh
+
+
+

This is imperative style: we tell the script to run these +steps in precisely this order, as we would run them manually, one after another.

+
+

Discussion

+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

    + +
    • +
+
+
+
+
+

Workflow tools

+

Sometimes it may be helpful to go from imperative to declarative style. Rather than saying “do this and then that” we describe dependencies but we let the tool figure out the series of steps to produce results.

+
+

Example workflow tool: Snakemake

+

Snakemake (inspired by GNU Make) is one of many tools to create reproducible and scalable data analysis workflows. Workflows are described via a human readable, Python based language. +Snakemake workflows scale seamlessly from laptop to cluster or cloud, without the need to modify the workflow definition.

+

A demo

+
+

Preparation

+

The exercise (below) and pre-exercise discussion uses the +word-count repository +(https://github.com/coderefinery/word-count) which we need to clone to work on it.

+

If you want to do this exercise on your own, you can do so either on your own computer (follow the instructions in the bottom right panel on the CodeRefinery installation instruction page), or the Binder +cloud service:

+

On your own computer:

+
    +

  • Install the necessary tools

    • +

  • Activate the coderefinery conda environment with conda activate coderefinery.

    • +

  • Clone the word-count repository:

    +
    $ git clone https://github.com/coderefinery/word-count.git
+
    +
    +

Workflow-1: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution in the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

We can see that Snakemake uses declarative style: +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Steps:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

    10. +
+ +
+
+
+

Visualizing the workflow

+

We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the --dag option, which will output the DAG in dot language.

+

Note: This requires the Graphviz software, +which can be installed by conda install graphviz.

+
$ snakemake -j 1 --dag | dot -Tpng > dag.png
+
+
+

Rules that have yet to be completed are indicated with solid outlines, while already completed rules are indicated with dashed outlines.

+
+Snakemake DAG +
+
+
+

Why Snakemake?

+
    +

  • Gentle learning curve.

    • +

  • Free, open-source, and installs easily via conda or pip.

    • +

  • Cross-platform (Windows, MacOS, Linux) and compatible with all High Performance Computing (HPC) schedulers: +same workflow works without modification and scales appropriately whether on a laptop or cluster.

    • +

  • Heavily used in bioinformatics, but is completely general.

    • +

  • Is is possible to define isolated software environments per rule, see here.

    • +

  • Also possible to run workflows in Docker or Apptainer containers.

    • +

  • Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up.

    • +

  • If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel.

    • +

  • Nice functionality for archiving the workflow, see: the official documentation

    • +
+

Tools like Snakemake help us with reproducibility by supporting us with automation, scalability and portability of our workflows.

Tools and what problems they try to solve

+

Conda, Anaconda, pip, virtualenv, Pipenv, pyenv, Poetry, requirements.txt, +environment.yml, renv, …, these tools try to solve the following problems:

+
    +

  • Defining a specific set of dependencies, possibly with well defined versions

    • +

  • Installing those dependencies mostly automatically

    • +

  • Recording the versions for all dependencies

    • +

  • Isolate environments

    +
      +

    • On your computer for projects so they can use different software

      • +

    • Isolate environments on computers with many users (and allow self-installations)

      • +
    +
    • +

  • Using different Python/R versions per project

    • +

  • Provide tools and services to share packages

    • +
+

Isolated environments are also useful because they help you make sure +that you know your dependencies!

+

If things go wrong, you can delete and re-create - much better +than debugging. The more often you re-create your environment, the +more reproducible it is.

+
+

Exercises

+
+

(optional) Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+

Answer in the collaborative document:

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click
+  - python
+  - pip
+  - pip:
+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4

+
    +
    +

    E: +You find a environment.yml file with:

(optional) Dependencies-2: Create a time-capsule for the future

+

Now it is time to create your own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+
+

What is a container?

+

Imagine if you didn’t have to install things yourself, but instead you could +get a computer with the exact software for a task pre-installed? Containers +effectively do that, with various advantages and disadvantages. They are +like an entire operating system with software installed, all in one file,

+He said, then we will ship your machine. And that's how Docker was born. +

  • Container definition files <-> like a blueprint to build a kitchen with all +utensils in which the recipe can be prepared.

+

From definition files to container images to containers

+
    +

  • Containers can be built to bundle all the necessary ingredients (data, code, environment, operating system).

    • +

  • A container image is like a piece of paper with all the operating system on it. When you run it, +a transparent sheet is placed on top to form a container. The container runs and writes only on +that transparent sheet (and what other mounts have been layered on top). When you are done, +transparency is thrown away. It can be repeated as often as you want, and base is always the same.

    • +

  • Definition files (e.g. Dockerfile or Singularity definition file) are text +files that contain a series of instructions to build container images.

    • +
+
+
+

You may have use for containers in different ways

+
    +

  • Installing a certain software is tricky, or not supported for your operating system? -> See if an image is available and run the software from a container instead!

    • +

  • You want to make sure your colleagues are using the same environment for running your code? -> Provide them an image of your container!

    +
      +

    • If this does not work, because they are using a different architecture than you do? -> Provide a definition file for them to build the image suitable to their computers. This does not create the exact environment as you have, but in most cases similar enough.

      • +
    +
    • +
+
+
+

The container recipe

+

Here is an example of a Singularity definition file (reference):

+
Bootstrap: docker
+From: ubuntu:20.04
+
+%post
+    apt-get -y update
+    apt-get -y install cowsay lolcat
+
+%environment
+    export LC_ALL=C
+    export PATH=/usr/games:$PATH
+
+%runscript
+    date | cowsay | lolcat
+
+
+

Popular container implementations:

+ +

They are to some extent interoperable:

+
    +

  • podman is very close to Docker

    • +

  • Docker images can be converted to Singularity/Apptainer images

    • +

  • Singularity Python can convert Dockerfiles to Singularity definition files

    • +
+
+
+
+

Pros and cons of containers

+

Containers are popular for a reason - they solve a number of +important problems:

+
    +

  • Allow for seamlessly moving workflows across different platforms.

    • +

  • Can solve the “works on my machine” situation.

    • +

  • For software with many dependencies, in turn with its own dependencies, +containers offer possibly the only way to preserve the +computational experiment for future reproducibility.

    • +

  • A mechanism to “send the computer to the data” when data is too

    • +

  • Installing software into a file instead of into your computer (removing +a file is often easier than uninstalling software if you suddenly regret an +installation)

    • +
+

However, containers may also have some drawbacks:

+
    +

  • Can be used to hide away software installation problems and thereby +discourage good software development practices.

    • +

  • Instead of “works on my machine” problem: “works only in this container” problem?

    • +

  • They can be difficult to modify (this is the focus of an exercise below)

    • +

  • Container images can become large

    • +
+
+

Danger

+

Use only official and trusted images! Not all images can be trusted! There +have been examples of contaminated images so investigate before using images +blindly. Apply same caution as installing software packages from untrusted +package repositories.

+
+
+
+
+

Where can one share or find images?

+ +
+
+
+

Exercises

+
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

(optional) Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash
+

Objectives

+
    +

  • Understand when tools discussed in this episode can be useful

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching/discussion

    • +
+
+

This episode presents a lot of different tools and opportunities for your research software project. +However, you will not always need all of them. As with so many things, it again depends on your project.

+
+

Important for every project

+
    +

  • Clear file structure for your project

    • +

  • At least consider the possibility that someone, maybe you may want to reproduce your work

    +
      +

    • Can you do something (small) to make it easier?

      • +

    • If you have ideas, but no time: add an issue to your repository; maybe someone else wants to help.

      • +
    +
    • +
+
+
+

Workflow tools will maybe make sense in the future

+
    +

  • In many cases, it is probably not needed

    • +

  • You will want to consider workflow tools:

    +
      +

    • When processing many files with many steps

      • +

    • Steps or files may change

      • +

    • Your main script, connecting your steps gets very long

      • +

    • …

      • +
    +
    • +
+
+
+

When should I worry about dependencies?

+
    +

  • Your code depends on multiple other packages

    • +

  • You want to avoid questions like: “What do I need to install to run your code”

    • +

  • You want help yourself running your code

    +
      +

    • After a few years

      • +

    • On a different computer

      • +

    • …

      • +
    +
    • +
+
+
+

Containers seem amazing, but do I have use for them?

+
    +

  • Maybe not yet, but knowing that you can …

    +
      +

    • Run Linux tools on your Windows computer

      • +

    • Run different versions of same software on your computer

      • +

    • Follow the “easy installation instructions” for an operating system that is not your own

      • +

    • Get a fully configured environment instead of only installing a tool

      • +

    • Share your setup and configurations with others +… can be very beneficial :)

Detailed day schedule

+

+ +

This was the schedule at workshop in March 2023 (2 hours and 15 minutes including 2x 10 min break):

+ +
+
+

Why we teach this lesson

+

Reproducibility in research is something that publishers, funding agencies, universities, +research leaders and the general public worries about and much is being written about it. +It is also something that researchers care deeply about - this lesson is typically one of the +most popular lessons in the pre-workshop survey.

+

Even though most PhD students, postdocs and researchers (i.e. typical workshop participants) +know about the importance of reproducibility in research, they often lack both a general +overview of what different aspects there are to reproducibility, and the knowledge of +specific tools that can be used for improving reproducibility.

+

Many participants may not adhere to good practices when organizing their projects, +and the “Organizing your projects” episode is meant to encourage participants to +structure their projects better. This may be obvious to some participants but it +doesn’t harm to preach to the choir.

+

Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people’s code to run), they +often don’t know or use good practices when it comes to recording dependencies. +Most participants also don’t use isolated environments for different projects and +don’t know why that can be important. +The episode “Recording dependencies” tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager.

+

Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +“Recording environments” introduces the concept of containers, and the optional +episode “Creating and sharing a container image” goes into details.

+

Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of “scientific workflows”, +and that there actually exist tools that help make such workflows reproducible. +The episode “Recording computational steps” introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible.

+
+
+

How to teach this lesson

+
+

How to start

+

Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we’re going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers).

+
+
+

Focus on concepts, and when to use which tool

+

Try to explain better what the different tools are useful for, but don’t go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem.

+
+
+
+

Typical pitfalls

+
+

Indentation in Snakefiles

+
    +

  • the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn’t matter +This works:

    • +
+
rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+
+

but this doesn’t work:

+
rule all:
+    input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+

nor this:

+
rule all:
+input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+
+
+
+

Field reports

+
+

2022 September

+

We used the strategy “absolutely minimal introductions, most time +for exercise”. Overall, it was probably the right thing to do since +there is so little time and so much to cover.

+

There wasn’t enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode.

+

The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn’t really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day.

    • +
+
+

This episode presents a lot of different tools and opportunities for your research software project. +However, you will not always need all of them. As with so many things, it again depends on your project.

+
+

Important for every project

+
    +

  • Clear file structure for your project

    • +

  • At least consider the possibility that someone, maybe you may want to reproduce your work

    +
      +

    • Can you do something (small) to make it easier?

      • +

    • If you have ideas, but no time: add an issue to your repository; maybe someone else wants to help.

      • +
    +
    • +
+
+
+

Workflow tools will maybe make sense in the future

+
    +

  • In many cases, it is probably not needed

    • +

  • You will want to consider workflow tools:

    +
      +

    • When processing many files with many steps

      • +

    • Steps or files may change

      • +

    • Your main script, connecting your steps gets very long

      • +

    • …

      • +
    +
    • +
+
+
+

When should I worry about dependencies?

+
    +

  • Your code depends on multiple other packages

    • +

  • You want to avoid questions like: “What do I need to install to run your code”

    • +

  • You want help yourself running your code

    +
      +

    • After a few years

      • +

    • On a different computer

      • +

    • …

      • +
    +
    • +
+
+
+

Containers seem amazing, but do I have use for them?

+
    +

  • Maybe not yet, but knowing that you can …

    +
      +

    • Run Linux tools on your Windows computer

      • +

    • Run different versions of same software on your computer

      • +

    • Follow the “easy installation instructions” for an operating system that is not your own

      • +

    • Get a fully configured environment instead of only installing a tool

      • +

    • Share your setup and configurations with others +… can be very beneficial :)

Recording computational steps

+
+

Questions

+
    +

  • You have some steps that need to be run to do your work. How do you +actually run them? Does it rely on your own memory and work, or is it +reproducible? How do you communicate the steps for future you and others?

    • +

  • How can we create a reproducible workflow?

    • +

  • When to use scientific workflow management systems.

Several steps from input data to result

+

The following material is partly derived from a HPC Carpentry lesson.

+

In this episode, we will use an example +project which finds most frequent +words in books and plots the result from those statistics. In this example we +wish to:

+
    +

  1. Analyze word frequencies using statistics/count.py +for 4 books +(they are all in the data directory).

    2. +

  2. Plot a histogram using plot/plot.py.

    3. +
+
+From book to word counts to plot +
+

Example (for one book only):

+
$ python statistics/count.py data/isles.txt > statistics/isles.data
+$ python plot/plot.py --data-file statistics/isles.data --plot-file plot/isles.png
+
+
+

Another way to analyze the data would be via a graphical user interface (GUI), where you can for example drag and drop files and click buttons to do the different processing steps.

+

Both of the above (single line commands and GUIs) are tricky in terms of reproducibility. We currently have two steps and 4 books. But imagine having 4 steps and 500 books. +How could we deal with this?

+

As a first idea we could express the workflow with a script. The repository includes such script called run_all.sh. +We can run it with:

+
$ bash run_all.sh
+
+
+

This is imperative style: we tell the script to run these +steps in precisely this order, as we would run them manually, one after another.

+
+

Discussion

+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

    + +
    • +
+
+
+
+
+

Workflow tools

+

Sometimes it may be helpful to go from imperative to declarative style. Rather than saying “do this and then that” we describe dependencies but we let the tool figure out the series of steps to produce results.

+
+

Example workflow tool: Snakemake

+

Snakemake (inspired by GNU Make) is one of many tools to create reproducible and scalable data analysis workflows. Workflows are described via a human readable, Python based language. +Snakemake workflows scale seamlessly from laptop to cluster or cloud, without the need to modify the workflow definition.

+
+
+
+
+

A demo

+
+

Preparation

+

The exercise (below) and pre-exercise discussion uses the +word-count repository +(https://github.com/coderefinery/word-count) which we need to clone to work on it.

+

If you want to do this exercise on your own, you can do so either on your own computer (follow the instructions in the bottom right panel on the CodeRefinery installation instruction page), or the Binder +cloud service:

+

On your own computer:

+
    +

  • Install the necessary tools

    • +

  • Activate the coderefinery conda environment with conda activate coderefinery.

    • +

  • Clone the word-count repository:

    +
    $ git clone https://github.com/coderefinery/word-count.git
+
    +
    +
    • +
+

On Binder: +We can also use the cloud service Binder to make sure +we all have the same computing environment. This is interesting from a +reproducible research point of view and it’s explained further in the Jupyter +lesson how this is even +possible.

+
    +

  • Go to https://github.com/coderefinery/word-count and click on the “launch binder” badge in the README.

    • +

  • Once it get started, you can open a new Terminal from the new menu (top right) and select Terminal.

    • +
+
+
+

Workflow-1: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution in the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

We can see that Snakemake uses declarative style: +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Steps:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

    10. +
+ +
+
+
+

Visualizing the workflow

+

We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the --dag option, which will output the DAG in dot language.

+

Note: This requires the Graphviz software, +which can be installed by conda install graphviz.

+
$ snakemake -j 1 --dag | dot -Tpng > dag.png
+
+
+

Rules that have yet to be completed are indicated with solid outlines, while already completed rules are indicated with dashed outlines.

+
+Snakemake DAG +
+
+
+

Why Snakemake?

+
    +

  • Gentle learning curve.

    • +

  • Free, open-source, and installs easily via conda or pip.

    • +

  • Cross-platform (Windows, MacOS, Linux) and compatible with all High Performance Computing (HPC) schedulers: +same workflow works without modification and scales appropriately whether on a laptop or cluster.

    • +

  • Heavily used in bioinformatics, but is completely general.

    • +

  • Is is possible to define isolated software environments per rule, see here.

    • +

  • Also possible to run workflows in Docker or Apptainer containers.

    • +

  • Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up.

    • +

  • If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel.

    • +

  • Nice functionality for archiving the workflow, see: the official documentation

    • +
+

Tools like Snakemake help us with reproducibility by supporting us with automation, scalability and portability of our workflows.

Tools and what problems they try to solve

+

Conda, Anaconda, pip, virtualenv, Pipenv, pyenv, Poetry, requirements.txt, +environment.yml, renv, …, these tools try to solve the following problems:

+
    +

  • Defining a specific set of dependencies, possibly with well defined versions

    • +

  • Installing those dependencies mostly automatically

    • +

  • Recording the versions for all dependencies

    • +

  • Isolate environments

    +
      +

    • On your computer for projects so they can use different software

      • +

    • Isolate environments on computers with many users (and allow self-installations)

      • +
    +
    • +

  • Using different Python/R versions per project

    • +

  • Provide tools and services to share packages

    • +
+

Isolated environments are also useful because they help you make sure +that you know your dependencies!

+

If things go wrong, you can delete and re-create - much better +than debugging. The more often you re-create your environment, the +more reproducible it is.

Exercises

+
+

(optional) Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+

Answer in the collaborative document:

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click
+  - python

+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4

+    - git+https://github.com/anotheruser/anotherproject.git@sometag
+
    +
    +

    E: +You find a environment.yml file with:

    +
    name: student-project
+channels:

+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4

+  - someproject=1.2.3
+  - anotherproject=2.3.4
+
    +
    +
    + +
    • +
+
+
+

(optional) Dependencies-2: Create a time-capsule for the future

+

Now it is time to create your own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+
+
+

What is a container?

+

Imagine if you didn’t have to install things yourself, but instead you could +get a computer with the exact software for a task pre-installed? Containers +effectively do that, with various advantages and disadvantages. They are +like an entire operating system with software installed, all in one file,

+
+He said, then we will ship your machine. And that's how Docker was born. +

From definition files to container images to containers

+
    +

  • Containers can be built to bundle all the necessary ingredients (data, code, environment, operating system).

    • +

  • A container image is like a piece of paper with all the operating system on it. When you run it, +a transparent sheet is placed on top to form a container. The container runs and writes only on +that transparent sheet (and what other mounts have been layered on top). When you are done, +transparency is thrown away. It can be repeated as often as you want, and base is always the same.

    • +

  • Definition files (e.g. Dockerfile or Singularity definition file) are text +files that contain a series of instructions to build container images.

    • +
+
+
+

You may have use for containers in different ways

+
    +

  • Installing a certain software is tricky, or not supported for your operating system? -> See if an image is available and run the software from a container instead!

    • +

  • You want to make sure your colleagues are using the same environment for running your code? -> Provide them an image of your container!

    +
      +

    • If this does not work, because they are using a different architecture than you do? -> Provide a definition file for them to build the image suitable to their computers. This does not create the exact environment as you have, but in most cases similar enough.

      • +
    +
    • +
+
+
+

The container recipe

+

Here is an example of a Singularity definition file (reference):

+
Bootstrap: docker
+From: ubuntu:20.04
+
+%post
+    apt-get -y update
+    apt-get -y install cowsay lolcat
+
+%environment
+    export LC_ALL=C
+    export PATH=/usr/games:$PATH
+
+%runscript
+    date | cowsay | lolcat
+
+
+

Popular container implementations:

+ +

They are to some extent interoperable:

+
    +

  • podman is very close to Docker

    • +

  • Docker images can be converted to Singularity/Apptainer images

    • +

  • Singularity Python can convert Dockerfiles to Singularity definition files

    • +
+
+
+
+

Pros and cons of containers

+

Containers are popular for a reason - they solve a number of +important problems:

+
    +

  • Allow for seamlessly moving workflows across different platforms.

    • +

  • Can solve the “works on my machine” situation.

    • +

  • For software with many dependencies, in turn with its own dependencies, +containers offer possibly the only way to preserve the +computational experiment for future reproducibility.

    • +

  • A mechanism to “send the computer to the data” when data is too

    • +

  • Installing software into a file instead of into your computer (removing +a file is often easier than uninstalling software if you suddenly regret an +installation)

    • +
+

However, containers may also have some drawbacks:

+
    +

  • Can be used to hide away software installation problems and thereby +discourage good software development practices.

    • +

  • Instead of “works on my machine” problem: “works only in this container” problem?

    • +

  • They can be difficult to modify (this is the focus of an exercise below)

    • +

  • Container images can become large

    • +
+
+

Danger

+

Use only official and trusted images! Not all images can be trusted! There +have been examples of contaminated images so investigate before using images +blindly. Apply same caution as installing software packages from untrusted +package repositories.

+
+
+
+
+

Where can one share or find images?

+ +
+
+
+

Exercises

+
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

(optional) Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash
+
    +

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

Recording dependencies

In dependencies.md:

+
+

(optional) Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+

Answer in the collaborative document:

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click
+  - python
+  - pip
+  - pip:
+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4
+  - sympy=1.4
+  - click=7.0
+  - python=3.8
+  - pip
+  - pip:
+    - git+https://github.com/someuser/someproject.git@d7b2c7e
+    - git+https://github.com/anotheruser/anotherproject.git@sometag
+
    +
    +

    E: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy=1.3.1
+  - numpy=1.16.4

(optional) Dependencies-2: Create a time-capsule for the future

+

Now it is time to create your own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

Detailed day schedule

Two example schedules for this lesson:

+

This is the planned schedule for the workshop in September 2023 (2 hours and 5 minutes including 10 min break) ; note that for this workshop, sharing code and data was moved to social coding lesson:

+ +

This was the schedule at workshop in March 2023 (2 hours and 15 minutes including 2x 10 min break):

+ +
+
+

Why we teach this lesson

+

Reproducibility in research is something that publishers, funding agencies, universities, +research leaders and the general public worries about and much is being written about it. +It is also something that researchers care deeply about - this lesson is typically one of the +most popular lessons in the pre-workshop survey.

+

Even though most PhD students, postdocs and researchers (i.e. typical workshop participants) +know about the importance of reproducibility in research, they often lack both a general +overview of what different aspects there are to reproducibility, and the knowledge of +specific tools that can be used for improving reproducibility.

+

Many participants may not adhere to good practices when organizing their projects, +and the “Organizing your projects” episode is meant to encourage participants to +structure their projects better. This may be obvious to some participants but it +doesn’t harm to preach to the choir.

+

Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people’s code to run), they +often don’t know or use good practices when it comes to recording dependencies. +Most participants also don’t use isolated environments for different projects and +don’t know why that can be important. +The episode “Recording dependencies” tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager.

+

Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +“Recording environments” introduces the concept of containers, and the optional +episode “Creating and sharing a container image” goes into details.

+

Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of “scientific workflows”, +and that there actually exist tools that help make such workflows reproducible. +The episode “Recording computational steps” introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible.

+
+
+

How to teach this lesson

+
+

How to start

+

Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we’re going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers).

+
+
+

Focus on concepts, and when to use which tool

+

Try to explain better what the different tools are useful for, but don’t go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem.

+
+
+
+

Typical pitfalls

+
+

Indentation in Snakefiles

+
    +

  • the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn’t matter +This works:

    • +
+
rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+
+

but this doesn’t work:

+
rule all:
+    input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+

nor this:

+
rule all:
+input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+
+
+
+

Field reports

+
+

2022 September

+

We used the strategy “absolutely minimal introductions, most time +for exercise”. Overall, it was probably the right thing to do since +there is so little time and so much to cover.

+

There wasn’t enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode.

+

The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn’t really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day.

Reproducible research - Preparing code to be usable by you and others in the future

+

Have you ever spent days trying to repeat the results from few weeks or months +ago? Or you have to do paper revisions, but you just can’t get the results to +match up? It’s unpleasant for both you and science.

+

In this lesson we will explore different methods and tools for better +reproducibility in research software and data. We will demonstrate how version +control, workflows, containers, and package managers can be used to record +reproducible environments and computational steps for our future selves.

+
+

A scary anecdote

+
    +

  • A group of researchers obtain great results and submit their work to a high-profile journal.

    • +

  • Reviewers ask for new figures and additional analysis.

    • +

  • The researchers start working on revisions and generate modified figures, but find inconsistencies with old figures.

    • +

  • The researchers can’t find some of the data they used to generate the original results, and +can’t figure out which parameters they used when running their analyses.

    • +

  • The manuscript is still languishing in the drawer …

    • +
+
+
+
+

Why talking about reproducible research?

+

A 2016 +survey +in Nature revealed that irreproducible experiments are a problem across all +domains of science:

+
+reproduciblity Nature +
+

This study is now few years old but the highlighted problem did not get +smaller.

+
+
+
+

Levels of reproducibility

A published article is like the top of a pyramid. It rests on multiple +levels that each contributes to its reproducibility.

This also means that you can think about it from the beginning of your research life cycle!

Organizing your projects

+
+

Objectives

+
    +

  • Get an overview on how to organize research projects

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching incl. discussions

    • +
+
+

One of the most basic steps to make your work reproducible is to organize your projects well. +Let’s go over some of the basic things which people have found to work (and not to work).

+
+

Directory structure for projects

+
    +

  • Project files in a single folder

    • +

  • Different projects should have separate folders

    • +

  • Use consistent and informative directory structure

    +
      +

    • Avoid spaces in directory and file names – it is uglier for humans but handy for computers.

      • +
    +
    • +

  • If you need to separate public/private, you can put them in public and private Git repos

    +
      +

    • If you need to separate public/secret, use .gitignore or a separate folder that’s not in Git

      • +
    +
    • +

  • Add a README file to describe the project and instructions on reproducing the results

    • +

  • If a software is reused in several projects it can make sense to put them in own repo

    • +
+

A project directory can look something like this:

+
project_name/
+├── README.md             # overview of the project
+├── data/                 # data files used in the project
+│   ├── README.md         # describes where data came from
+│   └── sub-folder/       # may contain subdirectories
+├── processed_data/       # intermediate files from the analysis
+├── manuscript/           # manuscript describing the results
+├── results/              # results of the analysis (data, tables, figures)
+├── src/                  # contains all code in the project
+│   ├── LICENSE           # license for your code
+│   ├── requirements.txt  # software requirements and dependencies
+│   └── ...
+└── doc/                  # documentation for your project
+    ├── index.rst
+    └── ...
+
+
+
+
+
+

Tracking source code, data, and results

+
    +

  • All code is version controlled and goes in the src/ or source/ directory

    • +

  • Include appropriate LICENSE file and information on software requirements

    • +

  • You can also version control data files or input files under data/

    • +

  • If data files are too large (or sensitive) to track, untrack them using .gitignore

    • +

  • Intermediate files from the analysis are kept in processed_data/

    • +

  • Consider using Git tags to mark specific versions of results (version +submitted to a journal, dissertation version, poster version, etc.):

    +
    $ git tag -a thesis-submitted -m "this is the submitted version of my thesis"
+
    +
    +
    • +
+ +
+
+
+

Reproducible publications

+
    +

  • Git can be used to collaborate on manuscripts written in, e.g., LaTeX and other text-based formats but other tools exist:

    +
      +

    • Overleaf: an online, collaborative LaTeX editor (has Git integration)

      • +

    • Authorea: collaborative platform for preprints (apparently also has Git integration)

      • +

    • HackMD: an online collaborative Markdown editor (has Git integration)

      • +

    • Manuscripts.io: a collaborative authoring tool that support scientific content and reproducibility.

      • +

    • Google Docs can be a good alternative

      • +
    +
    • +

  • Many tools exist to assist in making scholarly output reproducible:

    +
      +

    • rrtools: instructions, templates, and functions for writing a reproducible article or report with R.

      • +

    • Jupyter Notebooks: web-based computational environment for creating code and text based notebooks that can be used as, see also our Jupyter lesson later in this workshop. +supplementary material for articles.

      • +

    • Binder: makes a repository with Jupyter notebooks available in an executable environment (discussed later in the Jupyter lesson).

      • +

    • “Research compendia”: a set of good practices for +reproducible data analysis in R, but much is transferable to other languages.

      • +

Discussion on reproducibility

+
+

Discuss in collaborative document or with your team members

+

How do you collaborate on writing academic papers?

+
- Are you using version control for academic papers?
+  - ...
+  - ...
+  - (share your experience)
+
+- How do you handle collaborative issues e.g. conflicting changes?
+  - ...
+  - ...
+  - (share your experience)
+
+
+
+

Please write or discuss your ideas before opening solution!

+
+ +
+
+

Discuss in collaborative document or with your team members

+
- What tools are you using when organizing your projects?
+  - ...
+  - ...
+  - (share your experience)
+
+
+
+
+

Keypoints

+
    +

  • An organized project directory structure helps with reproducibility.

    • +

  • Reproducibility makes work easier for the next person working on the project - and that might be you in a few years!

Reproducible research - Preparing code to be usable by you and others in the future

+

Have you ever spent days trying to repeat the results from few weeks or months +ago? Or you have to do paper revisions, but you just can’t get the results to +match up? It’s unpleasant for both you and science.

+

In this lesson we will explore different methods and tools for better +reproducibility in research software and data. We will demonstrate how version +control, workflows, containers, and package managers can be used to record +reproducible environments and computational steps for our future selves.

+
+

+
By the end of this lesson, learners should:
    +

  • be able to apply well organized directory structure for their project

    • +

  • remember the FAIR principles

    • +

  • understand that code can have dependencies, and know how to document them

    • +

  • if a computational studies contains several steps, be able to document them

    • +

  • know about use cases for containers

    • +

  • knowing the pros and cons of manual documentation vs. scripted automation vs. workflow management

    • +
+
+
+
+

A scary anecdote

+
    +

  • A group of researchers obtain great results and submit their work to a high-profile journal.

    • +

  • Reviewers ask for new figures and additional analysis.

    • +

  • The researchers start working on revisions and generate modified figures, but find inconsistencies with old figures.

    • +

  • The researchers can’t find some of the data they used to generate the original results, and +can’t figure out which parameters they used when running their analyses.

    • +

  • The manuscript is still languishing in the drawer …

    • +
+
+
+
+

Why talking about reproducible research?

+

A 2016 +survey +in Nature revealed that irreproducible experiments are a problem across all +domains of science:

+
+reproduciblity Nature +
+

This study is now few years old but the highlighted problem did not get +smaller.

+
+
+
+

Levels of reproducibility

+

A published article is like the top of a pyramid. It rests on multiple +levels that each contributes to its reproducibility.

+
+Reproducibility pyramid +
+

+

This also means that you can think about it from the beginning of your research life cycle!

+
+
+

Discuss in collaborative document or with your team members

+
- What are your experiences re-running or adjusting a script or a figure you
+  created few months ago?
+  - ...
+  - ...
+  - (share your experience)
+
+- Have you continued working from a previous student's
+  script/code/plot/notebook? What were the biggest challenges?
+  - ...
+  - ...
+  - (share your experience, but constructively)

Organizing your projects

+
+

Objectives

+
    +

  • Get an overview on how to organize research projects

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching incl. discussions

    • +
+
+

One of the most basic steps to make your work reproducible is to organize your projects well. +Let’s go over some of the basic things which people have found to work (and not to work).

+
+

Directory structure for projects

+
    +

  • Project files in a single folder

    • +

  • Different projects should have separate folders

    • +

  • Use consistent and informative directory structure

    +
      +

    • Avoid spaces in directory and file names – it is uglier for humans but handy for computers.

      • +
    +
    • +

  • If you need to separate public/private, you can put them in public and private Git repos

    +
      +

    • If you need to separate public/secret, use .gitignore or a separate folder that’s not in Git

      • +
    +
    • +

  • Add a README file to describe the project and instructions on reproducing the results

    • +

  • If a software is reused in several projects it can make sense to put them in own repo

    • +
+

A project directory can look something like this:

+
project_name/
+├── README.md             # overview of the project
+├── data/                 # data files used in the project
+│   ├── README.md         # describes where data came from
+│   └── sub-folder/       # may contain subdirectories
+├── processed_data/       # intermediate files from the analysis
+├── manuscript/           # manuscript describing the results
+├── results/              # results of the analysis (data, tables, figures)
+├── src/                  # contains all code in the project
+│   ├── LICENSE           # license for your code
+│   ├── requirements.txt  # software requirements and dependencies
+│   └── ...
+└── doc/                  # documentation for your project
+    ├── index.rst
+    └── ...
+
+
+
+
+
+

Tracking source code, data, and results

+
    +

  • All code is version controlled and goes in the src/ or source/ directory

    • +

  • Include appropriate LICENSE file and information on software requirements

    • +

  • You can also version control data files or input files under data/

    • +

  • If data files are too large (or sensitive) to track, untrack them using .gitignore

    • +

  • Intermediate files from the analysis are kept in processed_data/

    • +

  • Consider using Git tags to mark specific versions of results (version +submitted to a journal, dissertation version, poster version, etc.):

    +
    $ git tag -a thesis-submitted -m "this is the submitted version of my thesis"
+
    +
    +
    • +
+ +
+
+
+

Reproducible publications

+
    +

  • Git can be used to collaborate on manuscripts written in, e.g., LaTeX and other text-based formats but other tools exist:

    +
      +

    • Overleaf: an online, collaborative LaTeX editor (has Git integration)

      • +

    • Authorea: collaborative platform for preprints (apparently also has Git integration)

      • +

    • HackMD: an online collaborative Markdown editor (has Git integration)

      • +

    • Manuscripts.io: a collaborative authoring tool that support scientific content and reproducibility.

      • +

    • Google Docs can be a good alternative

      • +
    +
    • +

  • Many tools exist to assist in making scholarly output reproducible:

    +
      +

    • rrtools: instructions, templates, and functions for writing a reproducible article or report with R.

      • +

    • Jupyter Notebooks: web-based computational environment for creating code and text based notebooks that can be used as, see also our Jupyter lesson later in this workshop. +supplementary material for articles.

      • +

    • Binder: makes a repository with Jupyter notebooks available in an executable environment (discussed later in the Jupyter lesson).

      • +

    • “Research compendia”: a set of good practices for +reproducible data analysis in R, but much is transferable to other languages.

Keypoints

+
    +

  • An organized project directory structure helps with reproducibility.

    • +

  • Reproducibility makes work easier for the next person working on the project - and that might be you in a few years!

+

Recording computational steps

+
+

Questions

+
    +

  • You have some steps that need to be run to do your work. How do you +actually run them? Does it rely on your own memory and work, or is it +reproducible? How do you communicate the steps for future you and others?

    • +

  • How can we create a reproducible workflow?

    • +

  • When to use scientific workflow management systems.

Several steps from input data to result

+

The following material is partly derived from a HPC Carpentry lesson.

+

In this episode, we will use an example +project which finds most frequent +words in books and plots the result from those statistics. In this example we +wish to:

+
    +

  1. Analyze word frequencies using statistics/count.py +for 4 books +(they are all in the data directory).

    2. +

  2. Plot a histogram using plot/plot.py.

    3. +
+
+From book to word counts to plot +
+

Example (for one book only):

+
$ python statistics/count.py data/isles.txt > statistics/isles.data
+$ python plot/plot.py --data-file statistics/isles.data --plot-file plot/isles.png
+
+
+
+

Discussion

+

We have two steps and 4 books. But imagine having 4 steps and processing 500 books. +Can you relate? Are you using similar setups in your research? How do you record them?

+
+
+

Kitchen analogy

+
+Busy kitchen +
+

Now we have many similar meals to prepare and possibly many chefs +present (cores) and workflow tools can help us to plan and document the steps +and run them efficiently. [Midjourney, CC-BY-NC 4.0]

Exercise

+
+

Exercise preparation

+

The exercise (below) and pre-exercise discussion uses a simple +word-count repository +(https://github.com/coderefinery/word-count). We should clone the +repository already to prepare to work on it.

+

You could do the exercise either on your own computer, or the Binder +cloud service:

+

On your own computer:

+
    +

  • Activate the coderefinery conda environment with conda activate coderefinery.

    • +

  • Clone the word-count repository:

    +
    $ git clone https://github.com/coderefinery/word-count.git
+
    +
    +
    • +
+

On Binder: +We can also use the cloud service Binder to make sure +we all have the same computing environment. This is interesting from a +reproducible research point of view and it’s explained further in the Jupyter +lesson how this is even +possible.

+
    +

  • Go to https://github.com/coderefinery/word-count and click on the “launch binder” badge in the README.

    • +

  • Once it get started, you can open a new Terminal from the new menu (top right) and select Terminal.

    • +
+
+
+

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

    • +
+ +
+
+

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books

+    input:
+        script='statistics/count.py',

+    log: 'plot/{file}.log'

+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

    10. +
+ +
+
+
+

Why Snakemake?

+
    +

  • Gentle learning curve.

    • +

  • Free, open-source, and installs easily via conda or pip.

    • +

  • Cross-platform (Windows, MacOS, Linux) and compatible with all HPC schedulers: +same workflow works without modification and scales appropriately whether on a laptop or cluster.

    • +

  • Heavily used in bioinformatics, but is completely general.

    • +

  • Is is possible to define isolated software environments per rule, see here.

    • +

  • Also possible to run workflows in Docker or Apptainer containers.

    • +

  • Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up.

    • +

  • If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel.

    • +

  • Nice functionality for archiving the workflow, see: the official documentation

    • +
+
+
+

Similar tools

+ +
+
+

Visualizing the workflow

+

We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the --dag option, which will output the DAG in dot language.

+

Note: This requires the Graphviz software, +which can be installed by conda install graphviz. It’s not necessary to +run this step yourself.

+
$ snakemake -j 1 --dag | dot -Tpng > dag.png
+
+
+

Tools and what problems they try to solve

+

Conda, Anaconda, pip, virtualenv, Pipenv, pyenv, Poetry, requirements.txt, +environment.yml, renv, …, these tools try to solve the following problems:

+
    +

  • Defining a specific set of dependencies, possibly with well defined versions

    • +

  • Installing those dependencies mostly automatically

    • +

  • Recording the versions for all dependencies

    • +

  • Isolate environments

    +
      +

    • On your computer for projects so they can use different software

      • +

    • Isolate environments on computers with many users (and allow self-installations)

      • +
    +
    • +

  • Using different Python/R versions per project

    • +

  • Provide tools and services to share packages

    • +
+

Isolated environments are also useful because they help you make sure +that you know your dependencies!

+

If things go wrong, you can delete and re-create - much better +than debugging. The more often you re-create your environment, the +more reproducible it is.

Exercises

+
+

(optional) Dependencies-1: Time-capsule of dependencies

+

Situation: 5 students (A, B, C, D, E) wrote a code that depends on a couple of libraries. +They uploaded their projects to GitHub. We now travel 3 years into the future +and find their GitHub repositories and try to re-run their code before adapting +it.

+

Answer in the collaborative document:

+
    +

  • Which version do you expect to be easiest to re-run? Why?

    • +

  • What problems do you anticipate in each solution?

    +
    +

    A: +You find a couple of library imports across the code but that’s it.

    +

    B: +The README file lists which libraries were used but does not mention +any versions.

    +

    C: +You find a environment.yml file with:

    +
    name: student-project
+channels:
+  - conda-forge
+dependencies:
+  - scipy
+  - numpy
+  - sympy
+  - click
+  - python

+    - git+https://github.com/someuser/someproject.git@master
+    - git+https://github.com/anotheruser/anotherproject.git@master
+
    +
    +

    D: +You find a environment.yml file with:

(optional) Dependencies-2: Create a time-capsule for the future

+

Now it is time to create your own time-capsule and share it with the future +world. If we asked you now which dependencies your project is using, what would +you answer? How would you find out? And how would you communicate this +information?

+
+

Try this either with your own project or inside the “coderefinery” conda +environment:

+
$ conda env export > environment.yml
+
+
+

Have a look at the generated file and discuss what you see.

+

In future you can re-create this environment with:

+
$ conda env create -f environment.yml

What is a container?

+

Imagine if you didn’t have to install things yourself, but instead you could +get a computer with the exact software for a task pre-installed? Containers +effectively do that, with various advantages and disadvantages. They are +like an entire operating system with software installed, all in one file,

+He said, then we will ship your machine. And that's how Docker was born. +

  • Container definition files <-> like a blueprint to build a kitchen with all +utensils in which the recipe can be prepared.

From definition files to container images to containers

+
    +

  • Containers can be built to bundle all the necessary ingredients (data, code, environment, operating system).

    • +

  • A container image is like a piece of paper with all the operating system on it. When you run it, +a transparent sheet is placed on top to form a container. The container runs and writes only on +that transparent sheet (and what other mounts have been layered on top). When you are done, +transparency is thrown away. It can be repeated as often as you want, and base is always the same.

    • +

  • Definition files (e.g. Dockerfile or Singularity definition file) are text +files that contain a series of instructions to build container images.

    • +
+
+
+

You may have use for containers in different ways

+
    +

  • Installing a certain software is tricky, or not supported for your operating system? -> See if an image is available and run the software from a container instead!

    • +

  • You want to make sure your colleagues are using the same environment for running your code? -> Provide them an image of your container!

    +
      +

    • If this does not work, because they are using a different architecture than you do? -> Provide a definition file for them to build the image suitable to their computers. This does not create the exact environment as you have, but in most cases similar enough.

      • +
    +
    • +
+
+
+

The container recipe

+

Here is an example of a Singularity definition file (reference):

+
Bootstrap: docker
+From: ubuntu:20.04
+
+%post
+    apt-get -y update
+    apt-get -y install cowsay lolcat
+
+%environment
+    export LC_ALL=C
+    export PATH=/usr/games:$PATH
+
+%runscript
+    date | cowsay | lolcat
+
+
+

Popular container implementations:

+ +

They are to some extent interoperable:

+
    +

  • podman is very close to Docker

    • +

  • Docker images can be converted to Singularity/Apptainer images

    • +

  • Singularity Python can convert Dockerfiles to Singularity definition files

    • +
+
+
+
+

Pros and cons of containers

+

Containers are popular for a reason - they solve a number of +important problems:

+
    +

  • Allow for seamlessly moving workflows across different platforms.

    • +

  • Can solve the “works on my machine” situation.

    • +

  • For software with many dependencies, in turn with its own dependencies, +containers offer possibly the only way to preserve the +computational experiment for future reproducibility.

    • +

  • A mechanism to “send the computer to the data” when data is too

    • +

  • Installing software into a file instead of into your computer (removing +a file is often easier than uninstalling software if you suddenly regret an +installation)

    • +
+

However, containers may also have some drawbacks:

+
    +

  • Can be used to hide away software installation problems and thereby +discourage good software development practices.

    • +

  • Instead of “works on my machine” problem: “works only in this container” problem?

    • +

  • They can be difficult to modify (this is the focus of an exercise below)

    • +

  • Container images can become large

    • +
+
+

Danger

+

Use only official and trusted images! Not all images can be trusted! There +have been examples of contaminated images so investigate before using images +blindly. Apply same caution as installing software packages from untrusted +package repositories.

+
+
+
+
+

Where can one share or find images?

+ +
+
+
+

Exercises

+
+

Containers-1: Time travel

+

Scenario: A researcher has written and published their research code which +requires a number of libraries and system dependencies. They ran their code +on a Linux computer (Ubuntu). One very nice thing they did was to publish +also a container image with all dependencies included, as well as the +definition file (below) to create the container image.

+

Now we travel 3 years into the future and want to reuse their work and adapt +it for our data. The container registry where they uploaded the container +image however no longer exists. But luckily we still have the definition file +(below)! From this we should be able to create a new container image.

+
    +

  • Can you anticipate problems using the definitions file 3 years after its creation? +Which possible problems can you point out?

    • +

  • Discuss possible take-aways for creating more reusable containers.

(optional) Containers-2: Explore two really useful Docker images

+

You can try the below if you have Docker installed. If you have +Singularity/Apptainer and not Docker, the goal of the exercise can be to run +the Docker containers through Singularity/Apptainer.

+
    +

  1. Run a specific version of Rstudio:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio
+
    +
    +

    Then open your browser to http://localhost:8787 +with login rstudio and password “yourpasswordhere” used in the previous +command.

    +

    If you want to try an older version you can check the tags at +https://hub.docker.com/r/rocker/rstudio/tags +and run for example:

    +
    $ docker run --rm -p 8787:8787 -e PASSWORD=yourpasswordhere rocker/rstudio:3.3
+
    +
    +
    2. +

  2. Run a specific version of Anaconda3 from +https://hub.docker.com/r/continuumio/anaconda3:

    +
    $ docker run -i -t continuumio/anaconda3 /bin/bash

Objectives

+
    +

  • Understand when tools discussed in this episode can be useful

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching/discussion

    • +
+
+

This episode presents a lot of different tools and opportunities for your research software project. +However, you will not always need all of them. As with so many things, it again depends on your project.

+
+

Important for every project

+
    +

  • Clear file structure for your project

    • +

  • At least consider the possibility that someone, maybe you may want to reproduce your work

    +
      +

    • Can you do something (small) to make it easier?

      • +

    • If you have ideas, but no time: add an issue to your repository; maybe someone else wants to help.

      • +
    +
    • +
+
+
+

Workflow tools will maybe make sense in the future

+
    +

  • In many cases, it is probably not needed

    • +

  • You will want to consider workflow tools:

    +
      +

    • When processing many files with many steps

      • +

    • Steps or files may change

      • +

    • Your main script, connecting your steps gets very long

      • +

    • …

      • +
    +
    • +
+
+
+

When should I worry about dependencies?

+
    +

  • Your code depends on multiple other packages

    • +

  • You want to avoid questions like: “What do I need to install to run your code”

    • +

  • You want help yourself running your code

    +
      +

    • After a few years

      • +

    • On a different computer

      • +

    • …

      • +
    +
    • +
+
+
+

Containers seem amazing, but do I have use for them?

+
    +

  • Maybe not yet, but knowing that you can …

    +
      +

    • Run Linux tools on your Windows computer

      • +

    • Run different versions of same software on your computer

      • +

    • Follow the “easy installation instructions” for an operating system that is not your own

      • +

    • Get a fully configured environment instead of only installing a tool

      • +

    • Share your setup and configurations with others +… can be very beneficial :)

Detailed day schedule

+

Two example schedules for this lesson:

+

This is the planned schedule for the workshop in September 2023 (2 hours and 5 minutes including 10 min break) ; note that for this workshop, sharing code and data was moved to social coding lesson:

+ +

This was the schedule at workshop in March 2023 (2 hours and 15 minutes including 2x 10 min break):

+ +
+
+

Why we teach this lesson

+

Reproducibility in research is something that publishers, funding agencies, universities, +research leaders and the general public worries about and much is being written about it. +It is also something that researchers care deeply about - this lesson is typically one of the +most popular lessons in the pre-workshop survey.

+

Even though most PhD students, postdocs and researchers (i.e. typical workshop participants) +know about the importance of reproducibility in research, they often lack both a general +overview of what different aspects there are to reproducibility, and the knowledge of +specific tools that can be used for improving reproducibility.

+

Many participants may not adhere to good practices when organizing their projects, +and the “Organizing your projects” episode is meant to encourage participants to +structure their projects better. This may be obvious to some participants but it +doesn’t harm to preach to the choir.

+

Even though many participants know that code can have many dependencies (e.g. they +may have experienced difficulties in getting other people’s code to run), they +often don’t know or use good practices when it comes to recording dependencies. +Most participants also don’t use isolated environments for different projects and +don’t know why that can be important. +The episode “Recording dependencies” tries to convey the importance of recording +dependencies accurately for your projects, and shows how tools like conda can be +used both as a package and software environment manager.

+

Many participants have heard about containers and find them interesting, but +lack an understanding of how they work or how they can be used. The episode +“Recording environments” introduces the concept of containers, and the optional +episode “Creating and sharing a container image” goes into details.

+

Many participants use complicated series of computational steps in their research +without realizing that this work falls into the category of “scientific workflows”, +and that there actually exist tools that help make such workflows reproducible. +The episode “Recording computational steps” introduces the concept of scientific +workflows, discusses various ways of managing workflows with varying degrees of +reproducibility, and shows how tools like Snakemake can be used to +both simplify workflows and make them more reproducible.

+
+
+

How to teach this lesson

+
+

How to start

+

Everyone knows that scientific results need to be reproducible, but not everyone is using +appropriate tools to ensure this. Here we’re going to get to know tools which help with +preserving the provenance of data and reproducibility on different levels, ranging from +workflow automation to software environment (containers).

+
+
+

Focus on concepts, and when to use which tool

+

Try to explain better what the different tools are useful for, but don’t go +into details. In this lesson we are not trying to gain expertise in the +various tools and master the details but rather we want to give an overview and +show that many tools exist and try to give participant the right feel for which +set of tools to approach for which type of problem.

+
+
+
+

Typical pitfalls

+
+

Indentation in Snakefiles

+
    +

  • the body of a rule and the body of an input keyword need to be indented, but the number of spaces doesn’t matter +This works:

    • +
+
rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+
+

but this doesn’t work:

+
rule all:
+    input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+

nor this:

+
rule all:
+input:
+    expand('statistics/{book}.data', book=DATA),
+    expand('plot/{book}.png', book=DATA)
+
+
+
+
+
+

Field reports

+
+

2022 September

+

We used the strategy “absolutely minimal introductions, most time +for exercise”. Overall, it was probably the right thing to do since +there is so little time and so much to cover.

+

There wasn’t enough time for the conda exercise (we could give only 7 +minutes), but also I wonder how engaging it is. We should look at how +to optimize the start of that episode.

+

The Snakemake episode went reasonably well. Our goal was 5 minutes +intro, long exercise, 5 minutes outro. The intro was actually a bit +longer, and there was the comment that we didn’t really explain what +Snakemake was before it started (though we tried). The start of this +episode should get particular focus in the future, since this is the +main exercise of the day.

Objectives

+
    +

  • Understand when tools discussed in this episode can be useful

    • +
+
+
+

Instructor note

    +

  • 10 min teaching/discussion

    • +
+
+

This episode presents a lot of different tools and opportunities for your research software project. +However, you will not always need all of them. As with so many things, it again depends on your project.

+
+

Important for every project

+
    +

  • Clear file structure for your project

    • +

  • At least consider the possibility that someone, maybe you may want to reproduce your work

    +
      +

    • Can you do something (small) to make it easier?

      • +

    • If you have ideas, but no time: add an issue to your repository; maybe someone else wants to help.

      • +
    +
    • +
+
+
+

Workflow tools will maybe make sense in the future

+
    +

  • In many cases, it is probably not needed

    • +

  • You will want to consider workflow tools:

    +
      +

    • When processing many files with many steps

      • +

    • Steps or files may change

      • +

    • Your main script, connecting your steps gets very long

      • +

    • …

      • +
    +
    • +
+
+
+

When should I worry about dependencies?

+
    +

  • Your code depends on multiple other packages

    • +

  • You want to avoid questions like: “What do I need to install to run your code”

    • +

  • You want help yourself running your code

    +
      +

    • After a few years

      • +

    • On a different computer

      • +

    • …

      • +
    +
    • +
+
+
+

Containers seem amazing, but do I have use for them?

+
    +

  • Maybe not yet, but knowing that you can …

    +
      +

    • Run Linux tools on your Windows computer

      • +

    • Run different versions of same software on your computer

      • +

    • Follow the “easy installation instructions” for an operating system that is not your own

      • +

    • Get a fully configured environment instead of only installing a tool

      • +

    • Share your setup and configurations with others +… can be very beneficial :)

Recording computational steps

+
+

Questions

+
    +

  • You have some steps that need to be run to do your work. How do you +actually run them? Does it rely on your own memory and work, or is it +reproducible? How do you communicate the steps for future you and others?

    • +

  • How can we create a reproducible workflow?

    • +

  • When to use scientific workflow management systems.

    • +
+
+
+

Instructor note

+
    +

  • 10 min teaching

    • +

  • 20 min exercises

    • +
+
+
+

Several steps from input data to result

+

The following material is partly derived from a HPC Carpentry lesson.

+

In this episode, we will use an example +project which finds most frequent +words in books and plots the result from those statistics. In this example we +wish to:

+
    +

  1. Analyze word frequencies using statistics/count.py +for 4 books +(they are all in the data directory).

    2. +

  2. Plot a histogram using plot/plot.py.

    3. +
+
+From book to word counts to plot +
+

Example (for one book only):

+
$ python statistics/count.py data/isles.txt > statistics/isles.data
+$ python plot/plot.py --data-file statistics/isles.data --plot-file plot/isles.png
+
+
+
+

Discussion

+

We have two steps and 4 books. But imagine having 4 steps and processing 500 books. +Can you relate? Are you using similar setups in your research? How do you record them?

+
+
+

Kitchen analogy

+
+Busy kitchen +
+

Now we have many similar meals to prepare and possibly many chefs +present (cores) and workflow tools can help us to plan and document the steps +and run them efficiently. [Midjourney, CC-BY-NC 4.0]

Exercise

+
+

Exercise preparation

+

The exercise (below) and pre-exercise discussion uses a simple +word-count repository +(https://github.com/coderefinery/word-count). We should clone the +repository already to prepare to work on it.

+

You could do the exercise either on your own computer, or the Binder +cloud service:

+

On your own computer:

+
    +

  • Activate the coderefinery conda environment with conda activate coderefinery.

    • +

  • Clone the word-count repository:

    +
    $ git clone https://github.com/coderefinery/word-count.git
+
    +
    +
    • +
+

On Binder: +We can also use the cloud service Binder to make sure +we all have the same computing environment. This is interesting from a +reproducible research point of view and it’s explained further in the Jupyter +lesson how this is even +possible.

+
    +

  • Go to https://github.com/coderefinery/word-count and click on the “launch binder” badge in the README.

    • +

  • Once it get started, you can open a new Terminal from the new menu (top right) and select Terminal.

    • +
+
+
+

Workflow-1: Scripted solution for processing 4 books

+

Somebody wrote a script (script.sh) to process all 4 books:

+
#!/usr/bin/env bash
+
+# loop over all books
+for title in abyss isles last sierra; do
+    python statistics/count.py data/${title}.txt > statistics/${title}.data
+    python plot/plot.py --data-file statistics/${title}.data --plot-file plot/${title}.png
+done
+
+
+

We can run it with:

+
$ bash script.sh
+
+
+
    +

  • What are the advantages of this solution compared to processing all one by one?

    • +

  • Is the scripted solution reproducible?

    • +

  • Imagine adding more steps to the analysis and imagine the steps being time consuming. What problems do you anticipate +with a scripted solution?

    • +
+ +
+
+

Workflow-2: Workflow solution using Snakemake

+
+How Snakemake works +
+

Somebody wrote a Snakemake solution +and the interesting file here is the Snakefile:

+
# a list of all the books we are analyzing
+DATA = glob_wildcards('data/{book}.txt').book
+
+rule all:
+    input:
+        expand('statistics/{book}.data', book=DATA),
+        expand('plot/{book}.png', book=DATA)
+
+# count words in one of our books
+rule count_words:
+    input:
+        script='statistics/count.py',
+        book='data/{file}.txt'
+    output: 'statistics/{file}.data'
+    conda: 'environment.yml'
+    log: 'statistics/{file}.log'
+    shell: 'python {input.script} {input.book} > {output}'
+
+# create a plot for each book
+rule make_plot:
+    input:
+        script='plot/plot.py',
+        book='statistics/{file}.data'
+    output: 'plot/{file}.png'
+    conda: 'environment.yml'
+    log: 'plot/{file}.log'
+    shell: 'python {input.script} --data-file {input.book} --plot-file {output}'
+
+
+

Snakemake uses declarative style: we describe dependencies but we let +Snakemake figure out the series of steps to produce results (targets). +Snakefiles contain rules that relate targets (output) to dependencies +(input) and commands (shell).

+

Exercise goals:

+
    +

  1. Clone the example to your computer: $ git clone https://github.com/coderefinery/word-count.git

    2. +

  2. Study the Snakefile. How does it know what to do first and what to do then?

    3. +

  3. Try to run it. Since version 5.11 one needs to specify number of cores (or +jobs) using -j, --jobs or --cores:

    +
    $ snakemake --delete-all-output -j 1
+$ snakemake -j 1
+
    +
    +

    The --delete-all-output part makes sure that we remove all generated files before we start.

    +
    4. +

  4. Try running snakemake again and observe that and discuss why it refused to rerun all steps:

    +
    $ snakemake -j 1
+
+Building DAG of jobs...
+Nothing to be done (all requested files are present and up to date).
+
    +
    +
    5. +

  5. Make a tiny modification to the plot.py script and run $ snakemake -j 1 again and observe how it will only re-run the plot steps.

    6. +

  6. Make a tiny modification to one of the books and run $ snakemake -j 1 again and observe how it only regenerates files for this book.

    7. +

  7. Discuss possible advantages compared to a scripted solution.

    8. +

  8. Question for R developers: Imagine you want to rewrite the two Python scripts and use R instead. Which lines in +the Snakefile would you have to modify so that it uses your R code?

    9. +

  9. If you make changes to the Snakefile, validate it using $ snakemake --lint.

    10. +
+ +
+
+
+

Why Snakemake?

+
    +

  • Gentle learning curve.

    • +

  • Free, open-source, and installs easily via conda or pip.

    • +

  • Cross-platform (Windows, MacOS, Linux) and compatible with all HPC schedulers: +same workflow works without modification and scales appropriately whether on a laptop or cluster.

    • +

  • Heavily used in bioinformatics, but is completely general.

    • +

  • Is is possible to define isolated software environments per rule, see here.

    • +

  • Also possible to run workflows in Docker or Apptainer containers.

    • +

  • Workflows can be pushed out to run on a cluster or in the cloud without modifications to scale up.

    • +

  • If several workflow steps are independent of each other, and you have multiple cores available, Snakemake can run them in parallel.

    • +

  • Nice functionality for archiving the workflow, see: the official documentation

    • +
+
+
+

+

Visualizing the workflow

+

We can visualize the directed acyclic graph (DAG) of our current Snakefile +using the --dag option, which will output the DAG in dot language.

+

Note: This requires the Graphviz software, +which can be installed by conda install graphviz. It’s not necessary to +run this step yourself.

+
$ snakemake -j 1 --dag | dot -Tpng > dag.png
+
+
+

Rules that have yet to be completed are indicated with solid outlines, while already completed rules are indicated with dashed outlines.
