mne.random_parcellation

mne.random_parcellation(subject, n_parcel, hemi, subjects_dir=None, surface='white', random_state=None)

Generate random cortex parcellation by growing labels.

This function generates a number of labels which don’t intersect and cover the whole surface. Regions are growing around randomly chosen seeds.

Parameters

subjectstr

Name of the subject as in SUBJECTS_DIR.

n_parcelint

Total number of cortical parcels.

hemistr

Hemisphere id (ie ‘lh’, ‘rh’, ‘both’). In the case of ‘both’, both hemispheres are processed with (n_parcel // 2) parcels per hemisphere.

subjects_dirstr | None

The path to the FreeSurfer subjects reconstructions. It corresponds to FreeSurfer environment variable SUBJECTS_DIR.

surfacestr

The surface used to grow the labels, defaults to the white surface.

random_stateNone | int | instance of RandomState

If random_state is an int, it will be used as a seed for RandomState. If None, the seed will be obtained from the operating system (see RandomState for details). Default is None.

Returns

labelslist of Label

Random cortex parcellation.
