Respected Sir , 

My work is focussed in the analysis of neuroimages. I ran a group of subject fmri data with Rest tools and obtained ALFF maps . I would like to know how to obtain the alff value for individual regions of the map and  parcellating it with Automated Anatomical Labeling (aal atlas) ? Is there a way to directly extract the ROI from the rest toolbox ?

Regards,

Anannya
