Hi, I'm playing around with different ways of generating custom annotation files using the fsaverage surface, and would like to estimate the surface area of each ROI. I tried running mris_anatomical stats, but it seems to required wm.mgz, which is not contained in the fsaverage directories (please see below). Is there any way around this? I'm really just interested in extracting the surface area for each label in my .annot file.
Thanks for your help, Alex
