It is possible, it is just not a good idea because if you map rh to lh and then compare to lh, the rh will have been interpolated to get it into the lh. Even if there are no differences between the two, you will see differences because of the interpolation. Mapping both to fsaverage_sym means that both will be interpolated. If this interpolation does not bother you, then I can show you how to get it from rh to lh. doug
