Hi, I run recon-all -autorecon1 on my own data set. I want to check the talairach transformation using tkregister2, but I don't have the "surf orig" (green lines) yet. My questions are: 1- How can I aligned the TARGET and MOVEABLE without the green lines? 2- Which of the 30 steps of recon-all -all creates the "surf orig"? 3- Would the best way to proceed be to run recon-all -all first to create the "surf orig" and then check talairach transform? thanks for your help, anne... a new user!
