Hi Martin,
Thanks for your answer. However, it seems to me that cortical thickness follow a particular process with the recon-all -long process, isn’t it ? Is there any resample onto average time subject then other operation following ?
Best regards, Matthieu

Hi Matthieu,
I never used PET data, but once you manage to resample you pet data onto the surface, you will have a file similar to the thickness file for each subjects. Instead of thickness it holds you PET information. From that point on everything should be identical to the thickness analysis.
So this is really more a question how to get your PET data sampled onto the surface. If no one else replies, write that into the subject line and repost.
Best, Martin

Dear Freesurfer’s experts,
I would like to use the longitudinal mixed-effects model for surface PET analysis. Although I could find all the process to follow the longitudinal analysis of cortical thickness, I couldn’t resolve the steps/commands to apply successively to coregistered PET data on T1 MRI.
Could you precise me the process and commands to use for PET longitudinal analysis ?
Many thanks in advance !
