true that approach i suggested wouldn't be optimal...i'm going to use my rois to track from the thalamus to the cortex so actually it would probably be better to take the intersection of cortical gray matter with the white matter below it and divide that region up into rois...same problem though, i suppose. anyhow let me know if you have any other ideas, haha.
