# Install
Conda is a package manager that can be installed on Linux, Windows, and Mac. If you have not yet installed conda on your computer, follow these instructions:
Conda Installation. Follow instructions for Miniconda. Use the Python 2.7 based installation.
Create an environment named walter:
conda create -n walter -c openalea openalea.lpy boost=1.66
Activate the walter environment (do not type 'source' on windows):
[source] activate walter
Install the different packages:
conda install -c openalea openalea.mtg alinea.caribu notebook matplotlib pandas scipy conda install -c openalea -c conda-forge pvlib-python pytables
Download the last version of astk:
git clone https://github.com/openalea-incubator/astk.git
Then, in the newly downloaded astk directory, run:
python setup.py install
Download WALTer from this repository, then, in the walter directory, run:
python setup.py install
or:
python setup.py develop
# Usage
If the WALTer environment in which you want to perform the simulations is not yet activated, do it, for instance (source may be optional, depending on the version of Conda):
conda -env list [source] conda activate
Create a project:
walter -p [project_name]
This will create a directory named project_name and, inside, it will save several files (default meteo data, geometric rules to create organs, output list).
Then you need to create a configuration file. This file has a header row and as many rows as simulations. Each genotype has its own set of parameters (one per column).
Run simulations (first, enter the directory created just before, and run the following command):
walter -i [sim_scheme.csv]
Enjoy the outputs!
Once done, desactivate the Condaenvironment:
[source] conda deactivate
Simple usage:
from WALTer import *# Acknowledgments
