nilearn.datasets.fetch_atlas_smith_2009#

nilearn.datasets.fetch_atlas_smith_2009(data_dir=None, mirror='origin', url=None, resume=True, verbose=1)[source]#

Download and load the Smith ICA and BrainMap Probabilistic atlas (2009).

See [1] and [2].

Parameters:
data_dirpathlib.Path or str, optional

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

mirrorstr, optional

By default, the dataset is downloaded from the original website of the atlas. Specifying “nitrc” will force download from a mirror, with potentially higher bandwidth. Default=’origin’.

urlstr, optional

URL of file to download. Override download URL. Used for test only (or if you setup a mirror of the data). Default=None.

resumebool, optional

Whether to resume download of a partly-downloaded file. Default=True.

verboseint, optional

Verbosity level (0 means no message). Default=1.

Returns:
datasklearn.utils.Bunch

Dictionary-like object, contains:

  • ‘rsn20’: str, path to nifti file containing the 20-dimensional ICA, resting-fMRI components. The shape of the image is (91, 109, 91, 20).

  • ‘rsn10’: str, path to nifti file containing the 10 well-matched maps from the 20 maps obtained as for ‘rsn20’, as shown in [1]. The shape of the image is (91, 109, 91, 10).

  • ‘bm20’: str, path to nifti file containing the 20-dimensional ICA, BrainMap components. The shape of the image is (91, 109, 91, 20).

  • ‘bm10’: str, path to nifti file containing the 10 well-matched maps from the 20 maps obtained as for ‘bm20’, as shown in [1]. The shape of the image is (91, 109, 91, 10).

  • ‘rsn70’: str, path to nifti file containing the 70-dimensional ICA, resting-fMRI components. The shape of the image is (91, 109, 91, 70).

  • ‘bm70’: str, path to nifti file containing the 70-dimensional ICA, BrainMap components. The shape of the image is (91, 109, 91, 70).

  • ‘description’: str, description of the atlas.
