msmbuilder.clustering.deterministic_subsample

msmbuilder.clustering.deterministic_subsample(trajectories, stride, start=0)

Given a list of trajectories, return a single trajectory shrink_multiple times smaller than the total number of frames in trajectories by taking every “stride”th frame, starting from “start”

Note that this method will modify the trajectory objects that you pass in

Parameters:

trajectories : list of msmbuilder.Trajectory

trajectories to subsample from

stride : int

freq to subsample at

start : int

first frame to pick

Returns:

trajectory : msmbuilder.trajectory

shortened trajectory
