FloPro is a flow program. This repository is a supplement to our manuscript:

Contents

• code: a Python library and scripts for network flow and enrichment analysis
• condor: scripts for running the analyses in a HTCondor cluster
• data: source and target gene lists for the network flow analysis

System dependencies

• Currently only Linux is officially supported and this package requires graphviz for some of its features, particularly the visualization of sets of enriched genes.

Install python dependencies

We have tested Python >= 3.8, but other Python 3's may work as well.

# setup virtual environment for flopro dependencies
python -m venv env
source env/bin/activate

# install dependencies
pip install -r requirements.txt

# install flopro
cd code/python
