Hi Doug, We conducted a cortical thickness analysis in patients versus controls and generated a group atrophy map. We additionally conducted a resting state functional connectivity study in volume space using healthy controls.
Ideally we would like to create a series of circular ROIs evenly distributed throughout our atrophy map in surface space to compare atrophy w/ connectivity values of the group-level connectivity map projected to the surface using mri_vol2surf. Any insight regarding the best way to make evenly-spaced ROIs, or if there is a better way to approach this analysis would be greatly appreciated. Victor Montal
