8.2.27. nilearn.datasets.fetch_surf_fsaverage

nilearn.datasets.fetch_surf_fsaverage(mesh='fsaverage5', data_dir=None)

Download a Freesurfer fsaverage surface. See [1].

Parameters
meshstr, optional

Which mesh to fetch. Default=’fsaverage5’.

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

  • ‘fsaverage5_sphere’: the low-resolution fsaverage5 spheres (10242 nodes)

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

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

data_dirstr, optional

Path of the data directory. Used to force data storage in a specified location.

Returns
datasklearn.datasets.base.Bunch
Dictionary-like object, the interest attributes are :

  • ‘pial_left’: Gifti file, left hemisphere pial surface mesh

  • ‘pial_right’: Gifti file, right hemisphere pial surface mesh

  • ‘infl_left’: Gifti file, left hemisphere inflated pial surface mesh

  • ‘infl_right’: Gifti file, right hemisphere inflated pial

    surface mesh

  • ‘sulc_left’: Gifti file, left hemisphere sulcal depth data

  • ‘sulc_right’: Gifti file, right hemisphere sulcal depth data
