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/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
