Hi Hugh, you can run mris_anatomical_stats passing it the sulc file as input. This will give you averages within aparc. I'm not sure what you mean by "measuring cortical folding". What measure would you accept? There's the sulcal depth and then there's curvature (?h.curv). There are two types of "normalization". One is intensity normalization which is a preprocessing step before the segmentation. "Normalization" is also refers to intersubject registration. Probably you mean the latter. doug
