nilearn.datasets.fetch_atlas_smith_2009¶

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

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

See Smith et al.[1] and Laird et al.[2].

Parameters:

data_dirpathlib.Path or str, optional: Path where data should be downloaded. By default, files are downloaded in a nilearn_data folder in the home directory of the user. See also nilearn.datasets.utils.get_data_dirs.
urlstr, default=None: URL of file to download. Override download URL. Used for test only (or if you setup a mirror of the data).
resumebool, default=True: Whether to resume download of a partly-downloaded file.
verboseint, default=1: Verbosity level (0 means no message).
mirrorstr, default=’origin’: 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.
dimensionint, optional: Number of dimensions in the dictionary. Valid resolutions available are {10, 20, 70}.
restingbool, default=True: Either to fetch the resting-fMRI or BrainMap components

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 Smith et al.[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 Smith et al.[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.

Warns:

DeprecationWarning: If a dimension input is provided, the current behavior (returning multiple maps) is deprecated. Starting in version 0.13, one map will be returned in a ‘maps’ dict key depending on the dimension and resting value.
