Hi Rujing, If you are looking for the cortical thickness measures of a subject, you can find it in that subject's freesurfer directory in the 'stats' folder. In there, you will find a file called ?h.aparc.stats - one for each hemisphere. Within the stats file, you'll see the Average thickness for various cortical regions as well as Mean Thickness of the entire cortex towards the top. The stats for the cortical regions determined by the Destrieux atlas are in the same directory.
I suggest looking at the ROI Analysis slides on this page: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial
And the tutorial about how to get the stats into a spreadsheet for analysis here: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROI
Please be sure to check over your data before analysis to make sure there are no errors that will affect your study. Allison
