mne.random_parcellation#
- 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.
- Parameters:
- subject
str
The FreeSurfer subject name.
- n_parcel
int
Total number of cortical parcels.
- hemi
str
Hemisphere id (ie ‘lh’, ‘rh’, ‘both’). In the case of ‘both’, both hemispheres are processed with (n_parcel // 2) parcels per hemisphere.
- subjects_dirpath-like |
None
The path to the directory containing the FreeSurfer subjects reconstructions. If
None
, defaults to theSUBJECTS_DIR
environment variable.- surface
str
The surface along which to do the computations, defaults to
'white'
(the gray-white matter boundary).- random_state
None
|int
| instance ofRandomState
A seed for the NumPy random number generator (RNG). If
None
(default), the seed will be obtained from the operating system (seeRandomState
for 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.
