Hi Christine,
yes that is essentially what is measure in ?h.sulc - the integrated signed
dot product of the movement vectors during inflation with the surface
normal (so outward movement in sulci is positive). Certainly you can
specify sulc in mris_anatomical_stats, although I can't remember if it is
in qdec or not.
cheers,
Bruce

Is there any way of measuring sulcal depth with FreeSurfer?
Or is sulcal depth simply measured by the positive values in ?h.sulc - i.e.
negative values are 'gyral heights' and positive values are 'sulcal depths'?
If so is it possible to calculate these values for certain parcellated
regions such as specific sulci in aparc?
Thanks for your help!
