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

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
