A Python library to facilitate path sampling algorithms.
OpenPathSampling (OPS) makes it easy to perform many variants of transition path sampling (TPS) and transition interface sampling (TIS), as well as other useful calculations for rare events, such as committor analysis and flux calculations. In addition, it is a powerful library to build new path sampling methods.
OPS is independent of the underlying molecular dynamics engine, and currently has support for OpenMM, as well as an internal engine suitable for 2D toy models.
Documentation is still in progress; if you have questions, please contact the development team.
To see the most recent updates to the code, see the release notes page on GitHub.
OPS was described in a pair of papers published in JCTC:
