Hello FreeSurfer experts,
I have many FS5.1 edited-subjects that I want to use in an application that only takes FS5.3 formatted statistics. I ran 20 subjects in FS51 and FS53. I took the FS51 subjects and reran recon-all -segstats (in FS53) and it updated aseg.stats closer to the values for FS53 native. I reran recon-all -parcstats but that didn't change the parcellation statistics. Correlations between FS51 updated and FS53 were ~r=0.91. It this a fair approach to take? Is there a fundamental difference between FS51 and FS53 that requires that I rerun/edit everything?

I can't remember all the differences:), but there might have been a change in how the estimated ICV is computed, and the partial volume correction may have changed. I general, I think it should be fine
