Dear FS experts,
I am running my first FS analysis and I'm trying to register my hippocampal subdivision volumes to my diffusion space image but cannot get good alignment. I ran my diffusion preprocessing in ExploreDTI so don't have the register.dat file automatically so created this using the bbregister tool and registered B0 image to my orig.mgz. I then used this dat to align my aseg to my diffusion space image and it worked well. The issue is when I try to use it to transform my hippocampal subfield volumes to diffusion space. They just don't line up. Is this due to the different FOV for the subfields? Can anyone advise how to get these volumes to transform correctly?
Any help would be greatly appreciated.
Thanks
Erik
