Hi Qi,
you should process both time points together via the freesurfer
longitudinal stream. Independent processing is less sensitive. Selecting
one of the time points as a template is also bad, as it induces
processing bias, see:

Hi All,
I was running freesurfer for a patient case of two time points. Will you
suggest to run it as a group, such as one time point as a template and
followed by longitudinal study, discussing atrophy or run these two time
points separately as two individual, running everything such recon-all,
