msmtools.dtraj.sample_indexes_by_sequence(indexes, sequence)

Samples trajectory/time indexes according to the given sequence of states

Parameters:

• indexes (list of ndarray( (N_i, 2) )) – For each state, all trajectory and time indexes where this state occurs. Each matrix has a number of rows equal to the number of occurrences of the corresponding state, with rows consisting of a tuple (i, t), where i is the index of the trajectory and t is the time index within the trajectory.
• sequence (array of integers) – A sequence of discrete states. For each state, a trajectory/time index will be sampled at which dtrajs have an occurrences of this state

Returns:

indexes – The sampled index sequence. Index array with a number of rows equal to N=len(sequence), with rows consisting of a tuple (i, t), where i is the index of the trajectory and t is the time index within the trajectory.

Return type:

ndarray( (N, 2) )
