Parcellating fMRI data in Nilearn with MICCAI atlas

I want to use nilearn to parcellate fMRI data with the MICCAI (Neuromorphometrics) atlas but it’s not included in the datasets library. What would be the easiest way to work around?
Thank you.

Hi @LLK,

Without knowing more about this atlas it is hard to give you a precise answer. But for a lot of atlas files, where it is a single image with different intensities representing different regions, you can create a masker for your fMRI data with nilearn.maskers.NiftiLabelsMasker. If it is a different kind of atlas image you can look into the other nilearn.maskers functions.

Thanks for responding so quickly, indeed, the nifti masker function does the job I needed. Thanks again! Leyla
