Hello,
I have 80 subjects' MRIs that were segmented in 2009 with a version of freesurfer that included this (cvs_version $Id: mri_segstats.c,v 1.11.2.5 2006/04/13 18:57:07 nicks Exp $) in the aseg.stats output. The other 19 of my subjects segmented in 2013 display this (cvs_version $Id: mri_segstats.c,v 1.33.2.5 2009/02/11 22:38:51 nicks Exp $) in the output. I think this latest version the 19 subjects were run on is freesurfer 4.4.0 but I'm not sure which freesurfer version the older segmentations were run on. The volumes I am looking at are significantly different between the subjects segmented in 2009 and those segmented in 2013. I would like to remove any bias in my data due to different software versions. Is there a way to know which freesurfer version output the older cvs_version so I can download that and resegment my 19 subjects to remove version bias? This would be much quicker than running all 100 subjects on the newest freesurfer version.
