Hi Caleb,
is this in a single subject or a group result? In a single subject
almost anything is expected. E.g. small motion can cause thickness
changes , so can hydration levels.
Best, Martin

Hello,
I'm tracking atrophy in the precentral region. I've run the subjects
through the longitudinal stream. Because of time constraints, I've
mostly focused on editing the precentral regions as well as any
significant errors outside of the region. I've observed increases in
thickness of up to 0.1mm in the precentral region. In some cases
there's an increase in volume as well. Upon inspection though, the
precentral wm/pial surfaces look fine. Is this a normal range of error?
Thank you,
-Caleb
