Hi everyone, I had two questions:
1) I was wondering if it's ok to run a glm to compare cortical surface areas between two groups on a vertex-wide basis (just like a thickness analysis). Or is it better to extract the area of a label (as is the output of mri_anatomical_stats)? 2) The mri_anatomical_stats output includes 4 measures of curvature: MeanCurv, GausCurv, Van Essen Folding index and Curvature Index. There was some discussion as to which of these was most appropriate for comparing sulcal folding (that is, essentially what they measure, correct?)- was there ever any final consensus? Thank you.
