I cannot replicate this on my data. The differences are rather extreme
(factors of 3). Can you get us access to the one with the largest
difference? YOu can also try regenerating the aseg.stats file, eg,
cd subject/
mri_segstats --seed 1234 --seg mri/aseg.mgz --sum stats/redo.aseg.stats
--pv mri/norm.mgz --empty --brainmask mri/brainmask.mgz
--brain-vol-from-seg --excludeid 0 --excl-ctxgmwm --supratent
--subcortgray --in mri/norm.mgz --in-intensity-name norm
--in-intensity-units MR --etiv --surf-wm-vol --surf-ctx-vol --totalgray
--euler --ctab /usr/local/freesurfer/7.2.0/ASegStatsLUT.txt --subject
subject
Check the eTIV in redo.aseg.stats against that in aseg.stats, then
re-run mri_sclimbic_seg to see if the results agree.

External Email - Use Caution
Hello,
I am getting different etiv values when running recon(orange) all VS
mri_sclimbic_seg (blue). My analysis uses limbic volumes extracted
from the dev version but I am not sure if I should just use the etiv
from recon all, given the data is tighter (see attached). Why is there
this discrepancy and what do you recommend?
Thank you!
