nilearn.datasets.fetch_surf_fsaverage#

nilearn.datasets.fetch_surf_fsaverage(mesh='fsaverage5', data_dir=None)[source]#

Download a Freesurfer fsaverage surface. File names are subject to change and only attribute names are guaranteed to be stable across nilearn versions. See 1.

Parameters

meshstr, optional

Which mesh to fetch. Should be one of the following values:

‘fsaverage3’: the low-resolution fsaverage3 mesh (642 nodes)

‘fsaverage4’: the low-resolution fsaverage4 mesh (2562 nodes)

‘fsaverage5’: the low-resolution fsaverage5 mesh (10242 nodes)

‘fsaverage6’: the medium-resolution fsaverage6 mesh (40962 nodes)

‘fsaverage7’: same as ‘fsaverage’

‘fsaverage’: the high-resolution fsaverage mesh (163842 nodes)

Note

The high-resolution fsaverage will result in more computation time and memory usage

Default=’fsaverage5’.

data_dirpathlib.Path or str, optional

Path where data should be downloaded. By default, files are downloaded in home directory.

Returns

datasklearn.datasets.base.Bunch
