My underlay is T1, the overlay is a stats map let's say for instance Fstats. I would like to add an ROI shown by box or edge such that one can visually check how well the stats map overlaps with the ROI. This ROI is given by a mask nii. What I could do with @chauffeur_afni so far is to have stats map on T1, stats map on ROI edge using -edgy_ulay, but how to plot these 3 things in one figure?
