Hi @tmedani !!
Thank you for your reply.
I made a mistake. The figure was 12-layer model.
After merge, I got this 5-layer model picture
In the 5-layer model picture, yellow is now blue, I think this is CSF area.
I think that T1 and T2 image is not that good. with visual check, this images have quite bad motion artifact. Would it be better to just exclude the subject at this point?
I can share you my protocol of this subject.
here is the google drive link!
Thanks a lot
Bong
