Dear FreeSurfer expert, 

 

I have compared the aseg volume between FreeSurfer 5.3 and FreeSurfer 6.0 with asegstatsdiff from FreeSurfer 6.0 for each subject in my data set. I have enclosed the range for some of the volume. I found the largest differences in subcortical structures, especially in Corpus callosum(CC). I found that FreeSurfer 6.0 CC posterior volume was 525.51 % larger than in FreeSurfer 5.3. Nevertheless, these differences were much smaller for lhCortex, but also here FreeSurfer 6.0 was on average larger than FreeSurfer 5.3. I ran the FreeSurfer 6.0 using the same option as FreeSurfer 5.30. Both versions of FreeSurfer were run on Centos. I am also enclosing a table with mean values along with min and max  for differences between FreeSurfer 5.3 and FreeSurfer 6.0 aseg volumes.
