Dear FreeSurfer Experts,

How could the longitudinal analysis be performed in order to show whether a parameter at time 1 is predictive of changes in cortical thickness over time ? and can the corresponding regions be shown in FreeSurfer ?

In a statistical analysis, as we see it, we must perform the correlation between the parameter at time 1 and the cortical thickness difference (or ROI) time 2-time 1, yet in this case we cannot see it on the cortex.

Thank you,
Alex
