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.

1) Is lh.lh-rh.thickness.sm00.mgh the stack of voxel-wise cortical thickness difference between left and right hemisphere of each subject?

2) 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)

3) 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)

4) Is there any way to look at the results through the brain per slice and also the whole brain?

Best regards,
Amirhossein Manzouri
