Hi Anirudh
you could tesselate them (using mri_tesselate or mri_ic) then compute the surface area of the tesselation, although this will be an overestimate due to the Cartesion voxels. We don't typically compute surface area of subcortical structures since volume is what people are more interested in

Hi, I am trying to find how to compute the area of subcortical structures like amygdala, hippocampus, thalamus etc. I have checked stats/aseg.stats file but it doesn't have areas. I looked at mri_asegstats and mris_anatomicalstats commands. Using mris_anatomicalstats I am able to compute surface area of cortical structures. But I am unable to figure out how to compute area of subcortical structures. Please suggest or give some pointers on how to achieve this. Thank you.
