protclus: Library for protein complex discovery on PPI networks

Project description

protclus - Minimal Python 3 library for Protein Complex Discovery in PPI Networks

This is a Python 3 library containing clustering algorithms chiefly used for protein complex discovery in protein-protein interaction (PPI) networks.

It is inspired by the collection of Python 2 scripts in (which is unfortunately due to deprecate in 2021) --- but updated for Python 3 and rewritten to as a set of classes and methods. As a result it is significantly easier to import and integrate into projects. Additionally it benefits from some additional flexibility in the output and some improvements on the speed of the algorithms.

It benefits from extremely simple usage that is shared between all of the methods

# Example using MCODE
filename = "data/unweighted_example_network.txt"
c = MCODE(filename)
