You should have a look at the 'aparcstats2table' command that comes with FreeSurfer, it does exactly what you want. There is no need to compute this manually.

Dear FreeSurfer experts:
I use the command recon-all qcache to get filesub_01/surf/lh.thickness.fwhm10.fsaverage.mgh file.
I want to know mean CT measures of every ROI after registraion in one subject. And I know mean CT is calculated by dividing CT of all vertices by the number of vertices.
Can I use fsaverage/label/?.annot as atlas to calculate mean cortical thickness of every ROI directly?
Or should I transfer sub_01/label/?.annot to fsaverage ?
