Hi Bruce,

We are working with a cohort of several hundred subjects, and all of the data has already been processed using the last version of FS. It would take quite a while for us to go through all of that data again, so we're trying to figure out if it would be okay to go ahead and use the longitudinal stream from 5.1 (sorry, not 5.0) using our current data, or if we really should, in fact, go back and start from scratch. Does that make sense? Sorry if I'm being unclear...

Hi Erica,

I'm not sure what you mean. Why not just run it through all the way? And we would *strongly* recommend using the 5.1 longitudinal instead of 5.0

cheers

Alright, thanks. Would you recommend against using the new longitudinal
stream with data generated from a previous version though? That is my main
question.

     no, there are other differences as well.

     Hi all,

     Does anyone have experience running a longitudinal
     analysis in version 5.0,
     using .mgz files generated from the last version of
     freesurfer? My
     understanding is that the only major differences between
     the previous and
     current versions were in the longitudinal stream. Any
     input would be
     appreciated! Thanks.
