Setting up environment

I developed and tested labyrinth on Fedora Linux version 38 and 39. While this package does not contain any operating system-specific code, it has not been tested on other operating systems. In theory, labyrinth should work on other Unix-like operating systems as long as the required dependencies are installed.

If you need to rebuild this model, it is strongly recommended to use Fedora Linux or its downstream operating system (i.e., Red Hat Enterprise Linux, CentOS Stream, Rocky Linux, Alma Linux) and follow the instructions above. Using a different environment may lead to unexpected issues or differences in results.

Red Hat Enterprise Linux, Rocky Linux, Alma Linux, and CentOS Stream

The Fedora RPMs for R have been ported to CentOS/RHEL by the project Extra Packages for Enterprise Linux (EPEL). These RPMs are also compatible with distributions derived from CentOS/RHEL. To use the EPEL repository, it is sufficient to download and install the appropriate epel-release RPM. Then R can be installed as described in the Fedora section.

  1. CentOS Stream 9

    sudo dnf config-manager --set-enabled crb
sudo dnf install epel-release epel-next-release -y

  2. Rocky Linux 9, AlmaLinux 9, and RHEL 9

    sudo dnf config-manager --set-enabled crb
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm -y

  3. CentOS Stream 8

    sudo dnf config-manager --set-enabled powertools
sudo dnf install epel-release epel-next-release -y

  4. Rocky Linux 8, AlmaLinux 8, and RHEL 8

    sudo dnf config-manager --set-enabled powertools
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm -y

  5. CentOS 7 and RHEL 7

    sudo yum-config-manager --enable extras
sudo yum install dnf -y
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm -y

Python 3

This R package relies on several Python packages. Users can install these packages using one of the following methods:

  1. System package manager on Linux

    # On Fedora, you can run:
sudo dnf install python3-numpy python3-sklearn python3-scipy python3-seaborn python3-tqdm python3-beautifulsoup4 python3-selenium python3-lxml 

# On Debian, you can run:
sudo apt install python3-numpy python3-sklearn-pandas python3-scipy python3-seaborn python3-tqdm python3-bs4 python3-selenium python3-lxml

  2. Python pip

    pip3 install numpy scikit-learn scipy seaborn tqdm beautifulsoup4 selenium lxml

  3. Anaconda / Miniconda

    conda create -n labyrinth numpy scikit-learn scipy seaborn tqdm beautifulsoup4 selenium lxml r-tidyverse r-devtools r-rcppeigen r-rcppprogress r-fastmatch r-rpca r-future.apply r-pbapply r-dbi r-rsqlite r-bursts r-patchwork r-furrr r-datapreparation r-tokenizers r-reticulate r-knitr r-progressr r-future.callr r-hrbrthemes r-proc r-ggthemes r-meta r-ggally r-matrixtests r-corrplot r-statix bioconductor-tcgabiolinks bioconductor-clusterprofiler bioconductor-fgsea bioconductor-deseq2 bioconductor-m3c -c bioconda -c conda-forge
conda activate labyrinth
Rscript -e "devtools::install_version('dbparser', version = '1.2.0')"
Rscript -e "remotes::install_github('randef1ned/word2vec')"

R

install.packages(c('tidyverse', 'devtools', 'igraph', 'future.apply', 'pbapply', 'DBI', 'RSQLite', 'bursts', 'patchwork', 'furrr', 'M3C', 'dataPreparation', 'tokenizers', 'reticulate', 'magrittr', 'knitr', 'progressr', 'future.callr', 'hrbrthemes', 'pROC', 'ggthemes', 'meta', 'GGally', 'matrixTests', 'rstatix', 'corrplot', 'BiocManager'))
devtools::install_version('dbparser', version = '1.2.0')
remotes::install_github('randef1ned/word2vec')
remotes::install_github('randef1ned/diffusr')

This project uses a custom fork of the diffusr package, which is maintained by @randef1ned. This fork optimizes the computational execution of the package, providing improved performance compared to the original version. View the documentation online.
