OpenFE Ecosystem Projects:#

openfe is Open Free Energy’s user-facing software for performing alchemical free energy calculations. Below are other software projects the Open Free Energy team maintains, many of which are used by openfe itself.

  • konnektor: free energy network planning, modification, and analysis

  • kartograf: atom mappings focusing on 3D geometries

  • Lomap: planning perturbation networks for free energy calculations

  • cinnabar (formerly arsenic): plotting free energy calculation results

  • gufe : data structures and models underlying the OpenFE ecosystem

Community-Developed Projects:#

  • alchemiscale: high-throughput alchemical free energy execution, developed by Datryllic.

  • feflow: Protocols and tooling based on openmmtools/perses and OpenFE, including a nonequilibrium cycling protocol with support for protein mutations.
