- mne.random_parcellation(subject, n_parcel, hemi, subjects_dir=None, surface='white', random_state=None)[source]#
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.
The FreeSurfer subject name.
Total number of cortical parcels.
Hemisphere id (ie
'both'). In the case of
'both', both hemispheres are processed with
(n_parcel // 2)parcels per hemisphere.

The path to the directory containing the FreeSurfer subjects reconstructions. If
None, defaults to the
The surface along which to do the computations, defaults to
'white'(the gray-white matter boundary).
int| instance of
A seed for the NumPy random number generator (RNG). If
None(default), the seed will be obtained from the operating system (see
RandomStatefor details), meaning it will most likely produce different output every time this function or method is run. To achieve reproducible results, pass a value here to explicitly initialize the RNG with a defined state.
