Installation

You can use JASS locally through the command line interface in a terminal. You need python3 to install and use JASS. As of May 2025, JASS runs on python from 3.8 to 3.12.

Installation with pip (recommended)

We advise users to install jass in a virtual environment

python3 -m venv $PATH_NEW_ENVIRONMENT
source $PATH_NEW_ENVIRONMENT/bin/activate
pip3 install git+https://gitlab.pasteur.fr/statistical-genetics/jass.git
pip3 install -r https://gitlab.pasteur.fr/statistical-genetics/jass/-/raw/master/requirements.txt

Additional software installation on Linux

Some python packages require additional non-python software that you might need to install, e.g. on Ubuntu, with:

sudo apt install libfreetype6-dev #(required by matplotlib)
sudo apt install libhdf5-dev #(required by tables)
