The first command loads the left hemisphere overlay onto the right hemisphere. Why do you want to do this?

As I mentioned before in my second question :
tksurfer fsaverage_sym rh inflated -aparc -overlay lh.lh-rh.thickness.sm00.mgh
tksurfer fsaverage_sym lh inflated -aparc -overlay lh.lh-rh.thickness.sm00.mgh
For Right and Left side!

I don't know what you mean by overlaying the results on L & R.
What is your command line?

Thanks Doug,
When I overlay the results on L & R , I see different patterns on
each hemisphere. Is it something that I don't understand correctly?

I don't know what you mean. Can you elaborate/

It is the difference between left and right hemisphere at
each vertex.

Do you mean mapping the difference into the volume and then
viewing it
as a volume? If so, You can try mri_surf2vol
