Dear Melanie, you can install the AAL atlas in SPM12 by running this: atlas_dir = fullfile(spm('Dir'),'atlas'); mkdir(spm('Dir'),'atlas'); untar('http://www.gin.cnrs.fr/AAL/aal_for_SPM12.tar.gz',atlas_dir); movefile(fullfile(atlas_dir,'aal_for_SPM12','AAL.*'),atlas_dir); then for a given binary image (one of your 256 ROIs), you can get AAL labels with: spm_atlas('list','installed','-refresh'); [Q,P] = spm_atlas('query','AAL','ROI_xx.nii'); where Q and P will contain the list of labels within the ROI and their proportions. If you need something more specific, just let us know more details about the files you have and the exact output you need. Best regards, Guillaume.
