SAGA_optimize runs under Python 3.6+ and is available through python3-pip. Install via pip or clone the git repo and install the following dependencies and you are ready to go!
python3 -m pip install SAGA-optimizeMake sure you have git installed:
git clone https://github.com/MoseleyBioinformaticsLab/SAGA_optimize.gitSAGA_optimize requires the following Python libraries:
- JSONPickle for saving Python objects in a JSON serializable form and outputting to a file.
