Hi Constantin, When you used tkregister2 which volume was the target? Acoording to what you write it was the b0 volume. So when you apply the registration to the T1 volume, you should keep it that way.
--mov T1 --targ b0image and no -inv is necessary. Let me know if I misunderstood what you were doing.
