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.

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
