Dear all, I am bit confused with the Qdec process. I finished recon all for 2 time points and want to create longitudinal data.From FS tutorial I learned to create within-subject templates for processing,which is running now with recon-all -base <templateID> -tp <tp1id> -tp <tp2id> ... -all. Now,in an other link of tutorial it says ,Qdec needs each subject to have a pre-computed smoothed data for the target surface ,recon-all -s <subjid> -qcache So my first is question is, recon-all -base <templateID> -tp <tp1id> -tp <tp2id> ... -all will do recon-all -s <subjid> -qcache along or I have to run it separately. Second,recon-all -base <templateID> -tp <tp1id> -tp <tp2id> ... -all is almost 12 hrs now and wondering if this is processing images from the very begining. Many Thanks chikku
