Dear FreeSurfers,
I have one question, related to longitudinal data processing. According to the wiki page about Longitudinal Processing, as the first step, all time points should be processed with the default workflow.
All of my data, including all time points, were already processed using FreeSurfer v. 4.0.2 and I would like to process the longitudinal data using v.5.0 or later. In this case, can I use the FS results from v. 4.0.2 as the input to the second step of longitudinal processing? OR, should I re-process my data with a new version from the first step?
Thank you very much for your help and answers in advance.
We always recommend to reprocess. In some cases it works to take older cross sectional data from an older version for longitudinal processing, but since 4.0.2 is rather old I would definitely recommend to reprocess.
Maybe best is to wait for 5.1 which will be out in a couple of weeks, if you reprocess anyway.
Best Martin
