Dear Freesurfer experts,

Based on the FS wiki, I calculated the cortical thickness difference between the lh and rh of a subject.
Now, I want to use the “mris_apply_reg” command to map the “left-right  difference” from fsaverage_sym back to the subject's native surface.
Unfortunately, I did not find the appropriate options of this command to do this work.
Thanks for any help.
 
Best regards,
Ali-Reza
