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.

Hi Rujing,

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