Hankee,
mris_volume will simply return the volume of the surface you request. You will have to do the subtraction, pial minus white, yourself.

I can't see the total gray matter volume in the ?h.aparc.stats file.If I run the mris_volume ?h.surface command in the
<subjid>/surf directory, It will produce the new file in this directory? which data will include in this file?
After that I use the formula:gm volume = pial volume - white volume to create the total gray matter volume? Am I right?
Thank you very much!

Hi Hankee,
You can use mris_volume to find this if you can’t get it from the aparc.stats:

This is reported in the ?h.aparc.stats file that is generated when the parcellation is run.
