msmtools.dtraj.save_dtraj

msmtools.dtraj.save_dtraj(filename, dtraj)

Write discrete trajectory to 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.
• dtraj (array-like of int) – Discrete state trajectory

load_discrete_trajectory()

Notes

The discrete trajectory is stored as ndarray of integers 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])

>>> os.unlink(tmpfile)
