Yea, I would not say it is the best way to do QC. But just correlating the
volumes themselves should be meaningful

Dear Eugenio,
I tested it on 103 subjects. The asymmetry index is significantly different
from 0 (symmetric) for both aseg and ThalamicNuclei.v12. Also when you
compare the asymmetry index across segmentation methods (either using
paired or independent
), MGH (HMS) and CSAIL (MIT)

Dear Eugenio,
Douglas referred me to you for this question. Do you have an
explanation for the difference in asymmetry between the native (aseg) and
ThalamicNuclei.v12 segmentation?
kind regards, Chris

I'm not sure about this. The FS segmentation atlas was not created to be
symmetrical, so interpreting the asymmetry of aseg results can be
tricky. I know that Eugenio often creates his atlases to be symmetric;
unfortunately, he's away until next week. Thalamus is also quite tricky
because the c

Dear freesurfer experts,
I’m currently using FreeSurfer 7.1 with the thalamus subsegmentation from
Iglesias et al (version 12) to subsegment the thalamus. Something we
noticed is that the asymmetry between the left and right whole thalamus is
reverse
