I see. There is really nothing to do but visually inspect them for
accuracy. Sorry, you will need to educate yourself a bit on what the
anatomy looks like to tell if the boundaries are accurate. It's really not
that difficult once you get a bit of experience. Feel free to send us
images that you have questions about if you want.

Dear professor Bruce,
Thanks for your attention.
After recon-all, I get the cortex thickness of all subjects. Then I check
the segmentations by
*
tkmedit your_subject_name brainmask.mgz -surfs -aseg.
However, my fundamental knowledge is so little that I donot know whether the
quality of segmented data I can use in further analysis. That is to say, I
donot know whether 3d structure of subjects is appropriate in further cortex
thickness analysis.
Thanks,
All the best.

Hi Rujing,
sorry, I don't understand. Can you clarify what you are trying to do?
