Hi Bruce,
Thanks for the quick response. The label is a manually traced area of the cortex. It is in subject scanner space and has a single value, so it probably would not work with bbregister. I can load it in tkmedit as a segmentation and the alignment is correct. I attached a screenshot. Is there a way to select the values greater than zero in tkmedit and save as a label that could be used in vol2surf? I have other labels that are larger so I would prefer not to retrace them if possible.
Best,
Jonathan
