External Email - Use Caution I reran sclimbic and I get the same result as the first time I ran sclimbic. I also reran recon all on one subject. The etiv now differs from the original recon all and the sclimbic output (although it is closer to sclimbic).
Here is the log for both recon all. original recon all, etiv = 1169944.199744 # cvs_version $Id: mri_segstats.c,v 1.121 2016/05/31 17:27:11 greve Exp $ # cmdline mri_segstats --seg mri/aseg.mgz --sum stats/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 /opt/freesurfer/ASegStatsLUT.txt --subject sub-1221084 # SegVolFileTimeStamp 2018/02/28 00:18:52 new etiv = 702243.513916 # cvs_version dev # cmdline mri_segstats --seed 1234 --seg mri/aseg.mgz --sum stats/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 /Applications/freesurfer/ASegStatsLUT.txt --subject sub-1221084 # SegVolFileTimeStamp 2022/07/25 21:04:31 sclimbic etiv= 686180.089200 >From a quick glance, the other values dont seem to differ by much between >recons so I'm not sure why this is happening with etiv nor what value to >accept.

Is this expected to happen? I am concerned if my volumes are incorrect. ________________________________ From: freesurfer-boun...@nmr.mgh.harvard.edu <freesurfer-boun...@nmr.mgh.harvard.edu> on behalf of Douglas N.

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.

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?
