Thank you Douglas and Tashrif!
Does this mean I should run recon-all for each subject several times,
and compute the average to get the more reliable thickness?
Can anyone else confirm this? Thanks!

Hi Xiaojiang and Douglas,
I think it is the attribute of having random initialization in the
registration
steps. This slight discrepancy can also be observed with antsRegistration.
I don't know the exact algorithm FreeSurfer uses for registration though.
Best,
Tashrif
