Hi Cathy,
please cc the freesurfer list when replying, so that other people can
profit from or contribute to the discussion.
(Maybe someone else can comment on the transfer of edits in cross
processing between versions 5.0.....5.3 ??)
So your cross data is processed with a mix of version 5 and 5.1? or is
all processed with 5.1? Within a study you should never mix versions,
ie. process some subjects with one versions others with a different
version. It is OK to mix some FS versions between the cross and long
processing, if it is done for all subjects the same way.
I think you have these options:
1. keep 5.1 cross sectional data (assuming all is 5.1) and run base and
long with 5.3. Then start processing base and long (qual check the base
and edit if necessary). It should also work if all cross data is in 5.0.
2. reprocess the cross sectionals with 5.3 keeping the edits. Check if
edits got transferred correctly, maybe edit more (or remove edits). Then
start the base and long (again qual check base and edit if necessary).
Obviously 1. would be less work. If you have mixed versions in your
cross data, I'd rather recommend 2.
Best, Martin
