Whu when I use "mris_anatomical_stats subjid lh", I get different result? Here average CT is 2.163+-0.898, while with 2 previous commands they were zeros.
number of vertices = 110852 total surface area = 71971 mm^2 total gray matter volume = 174387 mm^3 average cortical thickness = 2.136 mm +- 0.898 mm average integrated rectified mean curvature = 0.168 average integrated rectified Gaussian curvature = 0.133 folding index = 5368 intrinsic curvature index = 529.3 On Thu, Apr 5, 2012 at 1:25 PM, Nooshin Zadeh <nooshin.z...@gmail.com>wrote: > 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. > > > > Best Regards > --------------------------------------------------- > Nooshin N.
