You should never mix FreeSurfer versions according to the FAQ, see https://surfer.nmr.mgh.harvard.edu/fswiki/UserContributions/FAQ#Q.CanIrunsom...

    External Email - Use Caution        

Hello FreeSurfer experts,

I'm planning to run QDEC on Schizophrenia and controls. To do that I ran recon-all for few subjects in 2 different systems. Both systems have ubuntu 16.04 OS but different freesurfer versions. One is using FS version6 and other is FS version5.3.

Just for confirmation, I ran recon-all for the same subjects in 2 above said systems. Now both yield different values for the area. Here I have tabulated the values:

fsid Left-Lateral-Ventricle Left-Inf-Lat-Vent Left-Cerebellum-White-Matter Left-Cerebellum-Cortex Left-Thalamus-Proper Left-Caudate Left-Putamen Left-Pallidum 3rd-Ventricle 4th-Ventricle Brain-Stem Left-Hippocampus Left-Amygdala CSF Left-Accumbens-area Left-VentralDC Left-choroid-plexus Right-Lateral-Ventricle Right-Inf-Lat-Vent Right-Cerebellum-White-Matter Right-Cerebellum-Cortex Right-Thalamus-Proper Right-Caudate Right-Putamen Right-Pallidum Right-Hippocampus Right-Amygdala Right-Accumbens-area Right-VentralDC Right-choroid-plexus WM-hypointensities Optic-Chiasm CC_Posterior CC_Mid_Posterior CC_Central CC_Mid_Anterior CC_Anterior INSP015 16157.6 1227.3 11526.1 50572.8 6893 3228.3 5076.3 1927.7 2698.1 2577.8 17706.7 3525.3 1594.6 1164.3 538 4063.9 889.6 10616.9 1179.4 10638.1 50615.7 7252.9 3612.1 5719.7 1788.7 3852.7 1980.1 504.5 3762.4 748.8 728.9 194.4 854.8 393.8 393.9 425.8 1042.1 INSP015 16157.6 1227.3 11526.1 50572.8 6893 3228.3 5076.3 1927.7 2698.1 2577.8 17706.7 3525.3 1594.6 1164.3 538 4063.9 889.6 10616.9 1179.4 10638.1 50615.7 7252.9 3612.1 5719.7 1788.7 3852.7 1980.1 504.5 3762.4 748.8 728.9 194.4 854.8 393.8 393.9 425.8 1042.1

The above variation is because of different versions or each time freesurfer yields different values? Could you please educate me more on this. Because if the freesurfer version is the issue then I need to run all analysis in one system which will take a lot of time.
