netneurotools.civet.civet_to_freesurfer(brainmap, surface='mid', version='v1', freesurfer='fsaverage6', method='nearest', data_dir=None)[source]

Project brainmap in CIVET space to freesurfer fsaverage space.

Uses a nearest-neighbor projection based on the geometry of the vertices

Parameters:

  • brainmap (array_like) – CIVET brainmap to be converted to freesurfer space

  • surface ({'white', 'mid'}, optional) – Which CIVET surface to use for geometry of brainmap. Default: ‘mid’

  • version ({'v1', 'v2'}, optional) – Which CIVET version to use for geometry of brainmap. Default: ‘v1’

  • freesurfer (str, optional) – Which version of FreeSurfer space to project data to. Must be one of {‘fsaverage’, ‘fsaverage3’, ‘fsaverage4’, ‘fsaverage5’, ‘fsaverage6’}. Default: ‘fsaverage6’

  • method ({'nearest', 'linear'}, optional) – What method of interpolation to use when projecting the data between surfaces. Default: ‘nearest’

  • data_dir (str, optional) – Path to use as data directory. If not specified, will check for environmental variable ‘NNT_DATA’; if that is not set, will use ~/nnt-data instead. Default: None

Returns:

data – Provided brainmap mapped to FreeSurfer

Return type:

np.ndarray
