Hi Sam,

thickness is described in our PNAS paper, surface area is just the area of all the surface triangles, and volume is the product of the two. Curvature is a differential geometric measure we compute. The one called "curv" is the mean curvature spatially smoothed a bit.

cheers, Bruce

Hi All,

I have a very basic question. Could you please point me to a publication or relevant material that describes the relationship of the various parameters that mris_anatomical_stats outputs. To be precise, I wanted to know how measures like thickness, volume, area, curvature are related. Also, would these measures vary when done on a volume based level in comparison to a surface based approach ?

Thank you, Sam
