Jenifer,
I've attached a picture from one the slides showing what is stored in .sulc (except ignore the 'thickness' bit, that is stored in .thickness). You are correct in your interpretation of values.

Hi, Looking for a little clarification. Using qdec to look at group differences in the surface measure ?h.sulc. Large positive values in ?h.sulc indicate greater sulcal depth, right? Large negative values in ?h.sulc indicate something about gyri? Small negative values in ?h.sulc indicate transition from gyral to sulcal or sulcal to gyral?
Many thanks for any additional info, Jenifer
