smFRET Package

Our software package for smFRET and example smFRET data are available for download on GitHub.


Our code treats single-molecule time-binned FRET trajectories as hidden Markov processes, allowing one to determine the most likely FRET-value distributions of states and their interconversion rates based on probability alone. Source code available upon request.

HaMMy is available for download on GitHub.
