Hi Zhuangming, please remember to post to the list. Thanks! I don't
understand your question. What do you mean by the exterior, anterior,
posterior, etc, surfaces?

Hi Doug,
Thank you for your prompting response. Do you mean the computation
only calculate exterior surface of the cortical region ? The other
five surface (i.e. anterior, posterior, left, right, interior) are
excluded ?
Thanks!
Zhuangming

*主题:* Re: [Freesurfer] Surface area in aparc stats
By default, the surface area is computed from the white surface
(ie, boundary between WM and GM). It is possible to compute it
from the pial surface (ie, boundary between GM and background)

Hi all,
I need to know how is the SurfArea in ?h.aparc.stats calculated
by FreeSurfer? Since each cortical parcellation has its own
thickness in 3D space, does the surface area computation consider
both the exterior surface (i.e. the surface separating the gray
matter and the background) and the interior surface (i.e. the
surface separating the gray matter and the white matter)?
Thanks!
