pyemma.msm.io.write_dtraj(filename, dtraj)

Write discrete trajectory to ascii 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

read_discrete_trajectory()

Notes

The discrete trajectory is written to a single column ascii file with integer entries.

Examples

>>> from tempfile import NamedTemporaryFile
>>> from pyemma.msm.io import write_discrete_trajectory, load_discrete_trajectory

Use temporary file

>>> tmpfile = NamedTemporaryFile()

Discrete trajectory

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

Write to disk (as ascii file)

>>> write_discrete_trajectory(tmpfile.name, dtraj)

Read from disk

>>> X = read_discrete_trajectory(tmpfile.name)
>>> X
array([0, 1, 0, 0, 1, 1, 0])
