Hi Robby,
depends on what you are trying to achieve.
The first stats model we implemented was the 2-stage model (with a
linear fit inside each subject and then a cross sectional comparison of
the atrophy rates, ie. slopes of the fit). For the first step the
surface data (within-subject) is already in a common space (although not
smoothed yet) and no qcache is needed and for the second step it cannot
be done without first doing the first step.
Now we also have tools for linear mixed effects modelling. For that we
need all data (all time points from all subjects) in the fsaverage
space. Try using the -qcache command on the longitudinal directories
(e.g. together with the --long flag etc). That should do the trick.
Best, Martin

Dear FS-experts
Is there any command that I can use for caching my preprocessed data
in the recon-all longitudinal stream, since this is possible through
adding the -qcache option in the cross-sectional pipeline. Or maybe
this is already automatically done without adding any option to the
command?
Thank you
