msmbuilder.clustering._assign¶
- msmbuilder.clustering._assign(metric, ptraj, generator_indices)[source]¶
Assign the frames in ptraj to the centers with indices generator_indices
Parameters: metric : msmbuilder.metrics.AbstractDistanceMetric
A metric capable of handling ptraj
ptraj : prepared trajectory
ptraj return by the action of the preceding metric on a msmbuilder trajectory
generator_indices : array_like
indices (with respect to ptraj) of the frames to be considered the cluster centers.
Returns: assignments : ndarray
assignments[i] = j means that the i`th frame in ptraj is assigned to `ptraj[j]
distances : ndarray
distances[i] = j means that the distance (according to metric) from ptraj[i] to ptraj[assignments[i]] is j
