I understand.

Thanks for your response, Feifei!

Hi Feifei

we don't compute thickness using the method introudced by (MacDonald et al.2000). For that you can look at either our 1999 NeuroImage pair of papers or the 2000 PNAS paper.

Essentially surface area is just the average area of the triangles that the vertex is attached to, and then volume is thickness times surface area. There are some details that Anderson Winkler worked out, but that is the core of it.

Dear Freesurfer experts,

I want to know how Freesufer to compute the volume and area at each

vertex.

...

Are there any references? I just found the reference which introduces the measure of thickness(MacDonald et al.2000).

Any help with this would be greatly appreciated.

Best regards, Feifei
