Dear Freesurfer group I want to get cortical thickness, and I am confused between using these two command lines:
mris_anatomical_stats -t subjid/surf<http://ads.clicksor.com/search.php?q=surf>/lh.thickness -b subjid lh that gives following information number of vertices total surface area (mm^2) total gray matter volume (mm^3) average cortical thickness +- standard deviation (mm) integrated rectified mean curvature integrated rectified Gaussian curvature folding index intrinsic curvature index structure name 110852 71971 0 0.000 0.000 0.168 0.133 5368 529.3 /Users/christine/Result_FS_Corrected/N219c/surf/lh.white and mris_anatomical_stats -t subjid/label/lh.cortex.label -b subjid lh that gives following information number of vertices total surface area (mm^2) total gray matter volume (mm^3) average cortical thickness +- standard deviation (mm) integrated rectified mean curvature integrated rectified Gaussian curvature folding index intrinsic curvature index structure name 110852 71971 0 0.000 0.000 0.168 0.133 5368 529.3 /Users/christine/Result_FS_Corrected/N219c/surf/lh.white. Can you please guide me which one is the right one for measuring cortical thickness? Why for both of them (mean+-STD) is zero? Thanks in advance.
