I am using mri_segstats with the --ctab flag to extract dti and suvr values from a white matter hyperintensities parcellation. Running mri_segstats on the image and parcellation with --ctab only reports on non-empty segmentations. I want it to also report on the empty segmentations. 

Is there a flag or any other freesurfer commands that i can use? 

Summary: I want mri_segstats to report on non-empty and empty segmentations, not just the former. 

Cheers. 

cmdline mri_segstats --seg wmh_lobar.nii.gz --i subj_rescaled_wholecere_PET2T1_smooth.nii.gz --sum SUVR_WMH_lobar.stats --ctab WMColorLUT.ctab --pv norm.mgz
