Hi,

I have never tested compatibility with 5.1 and would recommend against it (5.1 was released almost 9 years ago). You can try it out on one subject and check results. There would be no support for this however.

Best, Martin

I think it should be ok in principle, though it might fail because the v6 long stream expects there to be certain files with certain names, and they might not be there with 5.1.

External Email - Use Caution

Dear Freesurfer Experts,

We have child data that was previously processed cross-sectionally using version 5.1. We are now interested in looking at the data longitudinally. Can the longitudinal processing stream in version 6.0 be used on data that was processed cross-sectionally using 5.1? Or is it better that we reprocess the data using 6.0. We appreciate any help you can provide!

Thank you,
