[Freesurfer] Negative eTIV

[lqcheng2017]

        External Email - Use Caution        

Dear experts,

I extracted the eTIV using the mri_segstats, but it showed negative value. How could I solve this problem?

Thank you very much.

cmdline mri_segstats --subject Gelb --etiv-only
UseRobust  0
atlas_icv (eTIV) = -2105 mm^3    (det: -925.465454 )

Best,

Luqi
