[Freesurfer] different results between 5.1.0 and 5.2.0

Dear FreeSurfer Experts

As in some other posts, I have also observed some differences between the two releases. The values from cuneus (thickness) are similar to the post from Ritobrato Datta, Ph.D. on 18 march.

But I also observed some differences in volume of right / left thalami. Did anybody observe such asymmetry?? I am now running analysis with patients and controls on data from 5.2.0 and got surprised with this asymmetry.

Here I am showing the average I obtained:

R PALLIDUM L PALLIDUM R THAL L THAL RH_CUNEUS LH_CUNEUS 5.1 (350 SUBJECTS) 1580 1688 6701 6970.31 1.845 1.857 5.2 (115 SUBJECTS, subgroup of 350) 1519 1367 6520 7401 2.42 2.40

Is there any approach to correct it on 5.2 ?? Thanks in advance clarissa
