DiFuMo atlas

Access

See nilearn.datasets.fetch_atlas_difumo.

Notes

We provide Dictionaries of Functional Modes “DiFuMo” (Dadi et al.[1]) that can serve as atlases to extract functional signals, e.g to serve as IDPs, with different dimensionalities (64, 128, 256, 512, and 1024). These modes are optimized to represent well raw BOLD timeseries, over a with range of experimental conditions.

• All atlases are available in .nii.gz format and sampled to MNI space

Additionally, we provide meaningful names for these modes, based on their anatomical location, to facilitate reporting of results.

• Anatomical names are available for each resolution in .csv
