Hi FreeSurfers,
I ran the longitudinal processing pipeline on my subjects, FS 5.0.
Following the tutorial, first independently, then base, then long etc.
Everything works well, no problems there.
Out of curiosity I compared the asegstats & aparcstats within subject at
baseline (i.e. The same t
Hi Cedric,
this is as expected, the data changes when using the longitudinal stream
(it will become more reliable, removing some of the variance you get in
the independent processing). Becuase of the different processing
approaches, the results from independent processing (cross) and long

This raises an interesting question.
Given that the longitudinal process is more reliable, if we collect 2 scans
on the same day, should we average those scans and then submit to
Freesurfer or apply Freesurfer first and then create an average of the
metrics from the longitudinal pipeline?

You should take the better of the two images (the one without motion
artifacts).
Cheers, Martin
