Dear Freesurfer experts, I would like to register surface data (an 'overlay' file) from fsaverage_sym space back to the subject's native rh.white surface. This seemed to work fine for the lh data using: mri_surf2surf --srcsubject fsaverage_sym --trgsubject fs8 --hemi lh --sval mysurfacedata_lh.gii --tval mysurfacedata_lh_native.mgh However, I am struggling to do this for the right hemisphere. Do you have any recommendations? Thank you in advance, Best, Felix
