8.2.7. nilearn.datasets.fetch_atlas_smith_2009

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

Download and load the Smith ICA and BrainMap atlas (dated 2009)

Parameters:

data_dir: string, optional

Path of the data directory. Used to force data storage in a non- standard location. Default: None (meaning: default)

mirror: string, 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 bandwith.

url: string, optional

Download URL of the dataset. Overwrite the default URL.

Returns:

data: sklearn.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)
