msmbuilder.tpt.fluxes¶

msmbuilder.tpt.fluxes(sources, sinks, msm, for_committors=None)¶

Compute the transition path theory flux matrix.

Parameters:	sources : array_like, int The set of unfolded/reactant states. sinks : array_like, int The set of folded/product states. msm : msmbuilder.MarkovStateModel MSM that has been fit to data. for_committors : np.ndarray, optional The forward committors associated with sources, sinks, and tprob. If not provided, is calculated from scratch. If provided, sources and sinks are ignored.
Returns:	flux_matrix : np.ndarray The flux matrix
