Hi Zhiliang

the thickness is the average of the min distance from gray-to-white and white-to-gray at each vertex. The surface area is the average area of the triangles attached to a vertex (divided by 3 I think).

Dear FS experts:
     I am writting to ask for help about the computation of global mean
thickness. On the FAQ page, one suggestion is that the global mean thickness
is equal to the (lh.thickness*lh.surfarea + rh.thickness.rh.surfarea) /
(lh.surfarea+rh.surfarea). I am wondering how the ?h.thickness and
?h.surfarea are calculated. 
    Any suggestions are appreciated.
    Thanks for your time.

Best
Zhiliang Long
