Hi,
It is hard to know what to do without more information.
What happens when you register?
Does it completely fail (brain out by 90 or 180 degrees)?
Or is it just out by a small amount (ventricle mismatch)?
Did you use BET on your anatomical image?
Is the result from BET good?
Have you got fieldmaps and are you applying distortion correction?
EPI and anatomical registration is not easy, but we can normally
get a pretty good alignment.
Let me know a few more details and we'll see what we can do.
All the best,
Mark
