number of regions of interest {100, 200, 300, 400 (default), 500, 600, 700, 800, 900, 1000}

yeo_networks: int

ROI annotation according to yeo networks {7 (default), 17}

resolution_mm: int

Spatial resolution of atlas image in mm {1 (default), 2}

data_dir: string

directory where data should be downloaded and unpacked.

base_url: string

base_url of files to download (None results in default base_url).

resume: bool

whether to resumed download of a partly-downloaded file.

verbose: int

verbosity level (0 means no message).

Returns
data: sklearn.datasets.base.Bunch

Dictionary-like object, contains:

  • maps: 3D Nifti image, values are indices in the list of labels.

  • labels: ROI labels including Yeo-network annotation,list of strings.

  • description: A short description of the atlas and some references.

Notes

Release v0.14.3 of the Schaefer 2018 parcellation is used by default. Versions prior to v0.14.3 are known to contain erroneous region label names.
