Hi Due to aberrantly high for a few of the subjects, I ran recon-all -autorecon2-wm -randomness -autorecon3 –hemi ?h before, calculating the localGI index. However, I intended to use these data in a longitudinal stream. These subject that were reprocessed using recon-all -autorecon2-wm -randomness -autorecon3 , and should I rerun the longitudinal stream for these subjects before doing I use recon-all –long id base_id –localGI? What are the optimal smoothing when using the linear mixed models?
Best regards Knut J Bjuland
