You might actually have to remap that to the subject’s volume using the individual surfaces and then back to the merged surface. The reason is that by merging the surfaces you change the topology, and in such a way that we cannot use surface registration to handle things. Tim may have additional ideas…
Why do you need to combine the surfaces in this way? Peace, Matt.

I'm tying to merge a smaller version of the Yeo2011 atlas annotation file from Freesurfer into a single gifti that I can overlay onto a gifti image with both Freesurfer hemispheres. I can merge the two hemispheres pretty easily with: mris_convert --combinesurfs lh.pial rh.pial Bothhemi.gii And I can convert the annotation files to giis pretty easily with: mris_convert --annot lh.ReducedYeo2011.annot lh.pial lh.ReducedYeo2011.gii But I can't then merge the separate annot files and project it onto the merged surface gifti. Either because it can't read the annot.gii or when it does it just projects it onto one hemisphere as a single value. Would anyone know how to do this conversion? Or alternatively, would it be easier to project a nii with the ROIs I'm interested in onto a surface with both hemispheres and then adjust accordingly? If so, how would I go about that?
