Re: [Freesurfer] Longitudinal BASE, missing data and potential time skew?

Hi Jacob, whenever there is is systematic difference, there is also potential for a bias. In your specific situation no one knows how large this bias could be. I would think it will not really be measurable, as the base is only used for initialisation and within such a small time frame, the

This contrast will do it: [1 -1 0 0] But I would first test [0 0 -1 1] to see if the slopes are different. If not, then use [1 -1 0] with DOSS instead of DODS On 12/14/2021 5:07 PM, Laura Willers de Souza wrote: External Email - Use Caution Yes! Sorry for that. And I'm resending my
