Hi Miggy, not sure about your first issue as the ribbon is the gray matter and the wm.mgz is white matter, so how would edits in one change the other? For the second one, there is a flag in mris_register that allows you to draw a label on an individual subject and indicate what parcellation u

Hi all, I'm trying to make a group average of a set of subjects that we've collected various functional data on and use anatomical landmarks of the group average surface to predict the locations of functional areas that we've found to be correlated to the anatomy of the ventral cortex. As such, we
