SurfArea is the surface area of the parcellation in mm^2.

GrayVol is the volume of gray matter in the parc (basically thickness time area) in mm^3

ThickAvg is the average thickness (use this for your thickness study)

MeanCurv is the average mean curvature.

GausCurv is the average gaussian curvature.
