msmtools.dtraj.load_dtraj

msmtools.dtraj.load_dtraj(filename)

Read discrete trajectory form binary file.

Parameters:filename (str) – The filename of the discrete state trajectory file. The filename can either contain the full or the relative path to the file. Returns:dtraj – Discrete state trajectory Return type:(M,) ndarray of int

save_discrete_trajectory()

Notes

The binary file is a one dimensional numpy array of integers stored in numpy .npy format.

Examples

>>> import numpy as np
>>> import os
>>> from tempfile import mktemp
>>> from msmtools.dtraj import load_discrete_trajectory, save_discrete_trajectory

Use temporary file

>>> tmpfile = mktemp(suffix='.npy')

Discrete trajectory

>>> dtraj = np.array([0, 1, 0, 0, 1, 1, 0])

Write to disk (as npy file)

>>> save_discrete_trajectory(tmpfile, dtraj)

Read from disk

>>> X = load_discrete_trajectory(tmpfile)
>>> X
array([0, 1, 0, 0, 1, 1, 0])
