Projects

Open Free Energy develops and maintains several software tools used in alchemical free energy calculations.

openfe

GitHub

Docs

This is the flagship product of Open Free Energy. This library contains tools to create, simulate, and analyze networks of alchemical transformations. It also includes a command line interface and interactive visualization tools.

Install with: conda install -c conda-forge openfe

gufe

GitHub

Gufe (grand unified free energy) is designed for use by developers of free energy methods. It provides object models for expressing the chemical systems and the alchemical transformations between them (mappings) to form free energy networks. Protocols can then be applied to provide an estimate of the free energy difference between different systems.

Install with: conda install -c conda-forge gufe

Cinnabar

GitHub

Cinnabar (previously arsenic) is a tool for the analysis and plotting of networks of free energy results. It was originally developed by Hannah Bruce Macdonald while working at the Chodera lab and is now maintained and developed by the Open Free Energy team.

Install with: conda install -c conda-forge cinnabar

lomap

GitHub

LOMAP is a tool for creating atom mappings between two ligand molecules. It was originally developed by the research lab of David Mobley at University of California, Irvine. Open Free Energy has taken responsibility for developing and maintaining this package.

Install with: conda install -c conda-forge lomap2
