msmbuilder.clustering.deterministic_subsample(trajectories, stride, start=0)[source]¶

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 mdtraj.Trajectory trajectories to subsample from stride : int freq to subsample at start : int first frame to pick
Returns:	trajectory : mdtraj.trajectory shortened trajectory
