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? BR

Dear Doug and FS experts, I am trying to use Xhemi tool to study asymmetry in the brain. I have done the exact procedure you mentioned in WiKi for a group of 40
controls.
- Is lh.lh-rh.thickness.sm00.mgh the stack of voxel-wise cortical
thickness difference between left and right hemisphere of each subject?
Yes.
- If yes, shouldn't I see the similar mapping by overlaying this to
lh and rh? (tksurfer fsaverage_sym rh inflated -aparc -overlay lh.lh-rh.thickness.sm00.mgh)
I don't know what you mean. Can you elaborate/
- How do you interpret the result after analyzing within one group?
( tksurfer fsaverage_sym lh inflated -aparc -overlay glm.lh.lh-rh.thickness.sm05/osgm/sig.mgh)
It is the difference between left and right hemisphere at each vertex.
- Is there any way to look at the results through the brain per slice
and also the whole brain?
Do you mean mapping the difference into the volume and then viewing it as a volume? If so, You can try mri_surf2vol doug
