The WhiteSurfaceArea is the area of the cortical surface defined as the boundary between the WM and the GM. Is this what you want?

Sorry, my mistake. I did mean surface area rather than volume. I am unsure as to how to find the total surface area of the cortical gray matter as ?.aparc.stats file only report WhiteSurfArea. Thanks, Will

The volume for each structure is given as the 4th column. If you want total GM volume, look in aseg.stats doug

Hi all,
I am a little unclear as to how to find the cortical grey matter volume in the stats output files. The ?.aparc.stats file shows:
Measure Cortex, WhiteSurfArea, White Surface Total Area, XXXX, mm^2
What about grey?
Thanks, Will
