8.2.9. 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 atlas (dated 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.

mirrorstring, 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.datasets.base.Bunch

Dictionary-like object, contains:

  • 20-dimensional ICA, Resting-FMRI components:

    • all 20 components (rsn20)

    • 10 well-matched maps from these, as shown in PNAS paper (rsn10)

  • 20-dimensional ICA, BrainMap components:

    • all 20 components (bm20)

    • 10 well-matched maps from these, as shown in PNAS paper (bm10)

  • 70-dimensional ICA, Resting-FMRI components (rsn70)

  • 70-dimensional ICA, BrainMap components (bm70)
