mne.labels_to_stc

mne.labels_to_stc(labels, values, tmin=0, tstep=1, subject=None, src=None, verbose=None)[source]

Convert a set of labels and values to a STC.

This function is meant to work like the opposite of extract_label_time_course.

Parameters
labelsLabel | BiHemiLabel | list | tuple | str

If using a surface or mixed source space, this should be the Label’s for which to extract the time course. If working with whole-brain volume source estimates, this must be one of:

  • a string path to a FreeSurfer atlas for the subject (e.g., their ‘aparc.a2009s+aseg.mgz’) to extract time courses for all volumes in the atlas

  • a two-element list or tuple, the first element being a path to an atlas, and the second being a list or dict of volume_labels to extract (see mne.setup_volume_source_space() for details).

Changed in version 0.21.0: Support for volume source estimates.

valuesndarray, shape (n_labels, …)

The values in each label. Can be 1D or 2D.

tminfloat

The tmin to use for the STC.

tstepfloat

The tstep to use for the STC.

subjectstr | None

The subject for which to create the STC.

srcinstance of SourceSpaces

The source spaces for the source time courses. Can be omitted if using a surface source space, in which case the label vertices will determine the output STC vertices. Required if using a volumetric source space.

New in version 0.22.

verbosebool | str | int | None

If not None, override default verbose level (see mne.verbose() and Logging documentation for more). If used, it should be passed as a keyword-argument only.

Returns
stcinstance of SourceEstimate | instance of VolSourceEstimate

The values-in-labels converted to a STC.

Notes

Vertices that appear in more than one label will be averaged.

New in version 0.18.
