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
