 # IMERGE-FEP
 This repository contains the code and files that form the basis of the manuscript "IMERGE-FEP: Improving Relative Free Energy Calculation Convergence with Chemical Intermediates"
 
-## Contents

-
-* rgroupinterm - a tool for pairwise R-group enumeration and pruning for the automatic creation of intermediate molecules
-* rhfe_gromacs - the code, input files and md files to run the free energy perturbations described in the manuscript
-* rhfe_analysis - code for analysing FEP output
-* data - raw data used as input
-* supplemental information - sdf files & visualization of molecules from the perturbations that were run
-* figures - code for manuscript figures

-* rgroup_enumeration.ipynb - documentation basic functionality enumerator
-* eg5_case_study.ipynb - application of enumerator on cogeneric series
-* perserving_chirality.ipynb - background on chiral information in RDkit
-* jacs_intermediates.py - script to enumerate all intermediates of the jacs files (takes a while)
-* calc_scores.py - calculates similarity scores of intermediates using the pruners (takes two days to run this for all intermediates in the jacs set)

 ## Installation
 Use setup.py for creating the environment for the intermediate generation
