free-energy-perturbation
Compute relative and absolute binding free energies with the Open Free Energy toolkit — the rigorous alchemical alternative to docking scores when a congeneric series needs reliable potency ranking. Use this skill to plan a perturbation network over a ligand set, choose atom mappings, run hybrid-topology or separated-topology protocols, and analyse the result — per-edge ΔΔG with uncertainty, cycle-closure error, and mean unsigned error against measured affinities. Also trigger on OpenFE, alchemical transformation, thermodynamic cycle, RBFE, ABFE, SepTop, lambda window, MBAR, cycle closure, or perturbation map.

- Compatibility
- Requires Python 3.10+. The bundled scripts plan networks and parse result JSON with the standard library only. Running a calculation needs openfe 1.12+ installed from conda-forge, docker, or singularity — note that `pip install openfe` fetches an unrelated 0.0.12 placeholder. An NVIDIA GPU is effectively mandatory — a single edge is hours of MD.
