is it not these two lines? # cvs_version $Id: mri_segstats.c,v 1.121 2016/05/31 17:27:11 greve Exp $ # cvs_version dev if not, for the new recon-all I also have this: freesurfer-darwin-macOS-dev-20220328-fc008d0
How do i check the old recon all? It was done in the past.is there a log?

What version of FS are you using for recon-all?

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

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.
Please let me know if there is something else I can do or if you need more info.

I am getting eerror: mri_segstats: could not open atlas transform file /export01/local/freesurfer/subjects/sub-1221084/mri/transforms/talairach.xfm The results do agree when Re running sclimbic.
it seems that when etiv differs a bit from the median, sclimbic module calculates etiv to an extreme. Is this expected to happen? I am concerned if my volumes are incorrect.

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.

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?
