Hello Freesurfers,

We would like to know how to calculate the total pial surface area for each hemisphere. We extracted the surface area from the 34 ROIs per hemi from lh.aparc.stats but there is no total pial surface area in that file (only white surface area). Does it make sense to just add the 34 ROIs or there's a better way to extract that measure?

Thanks! Mihaela
