Free-Energy-Perturbation-FEP

Scripts for running alchemical free-energy perturbation simulations using Gromacs.

runme.sh

Allows specification of host/queue and contains commands to prepare and submit simulations.

setup_lambda_jobs.py

Contains all information for writing batch files to be submitted to the queue.

mbar_analysis.sh

Copies all dhdl.xvg files into the respective mbar_analysis folder for each thermodynamic leg and runs mbar calculations on it from the alchemical-analysis repository. The resulting free energies are organized into a plottable output file with error bars, and the overall energies are also reported.

iterative_mbar.sh

Shows how the results converge when removing the first 1-15 picoseconds of simulation. (This one will take a few hours).
