Hi JohnMark
lots of things change between versions and it is not possible to go back unless you just run the old version

Hello, Recently, I re-ran recon-all with Freesurfer version 5 on some subjects whose surfaces had previously been reconstructed with Freesurfer version 4. As a result, it appears that their surface reconstructions have subtly changed, such that the labels that were specified in the old reconstruction are all messed up in the new reconstruction (since the surfaces that they were once associated with have changed). Did recon-all change between Freesurfer versions, and if so, is there a way to go back to the old algorithm short of simply switching back to Freesurfer version 4? It is possible that I have accidentally changed something else and that's why the surface files are different, but I wanted to see if there were any changes in the reconstruction algorithm between versions that might have caused this.
Thank you very much,
