When you look at the values that are produced by mris_anatomical_stats for surface area, are these values the same as pial surface area?
Is the pial surface the same as the inflated surface?

Hey Keyma,
the default surface is ?h.white. You can specify a different one (such as pial) by including it as the 3rd command line argument.
cheers, Bruce

So when you run it with the default ?h.white surface then it is computing the surface area of white matter? I'm confused then on what it is computing for the thickness, is this still the distance between the gray and white matter?

yes, the surface you specify only matters for surface area.

Is there any benefit to using the white surface for surface area. Why is that the default?

I guess we could have made it mandatory to specify one. There's no benefit, it just provides different information (presumably less sensitive to atrophy, which could be good or bad depending on your interest)
