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
