External Email - Use Caution Hi Douglas,
I see the CLUT file, it's the same one I've been using. I have been using FSL (fslmaths) to extract anatomical ROIs from the aparc+aseg using the CLUT indices as thresholds. This normally works, but results in empty ROIs for thalamic nuclei (but not for whole thalamus). What do you think could be the problem? Best, Ameen On Fri, Jul 17, 2020 at 10:33 AM Douglas N.
