FEP-suite: scripts and pipelines for free-energy perturbation calculation works

FEP-suite is a collection of programs for calculating various free energy differences. The pipeline uses GROMACS as a backend. There are currently two pipelines:

• ABFE (absolute binding free energy) estimator, calculating binding free-energy betweeen receptor and ligand (typically protein and drug).
• FEP/REST (free energy perturbation / replica exchange solute tempering), a relative free-energy difference calculation pipeline with an enhanced sampling technique.

Under both directory named abfe and feprest you can see README.md corresponding to each pipeline and how to use. Have fun!

Note the program is currently in "beta" version.
