not sure about --continuous, Rudolph will know. The quadratic patch stuff
is in mris_cuvature, but maybe also in mris_curvature_stats

Many thanks for that. Am I correct in thinking that the Gauss_Bonnet scheme
is given by the "--discrete" option in mris_curvature_stats, while the
latter option is given by the "--continuous" flag?

Hi Lisa,
we actually provide a discrete estimate using Gauss-Bonnet (Rudolph can
give you the details), and a slightly larger-scale estimate by fitting a
quadratic patch to each neighborhood (5mm on a side I think). The curvature
then comes from the Hessian of the height function of that patch.
