Hi Dave,
thank you for your reply.
Following previous post How to compute AFD? I also computed mrconvert fod.mif -coord 3 0 - | mrcalc 0.282 -divide afd.mif.
I thought the two steps fod2fixel+fixel2voxel would have helped constraining the fod-related information. But you are probably suggesting the first one is a better way to go.
I performed dwibiascorrection and global normalisation, however I haven’t built the FOD template. I thought I could still compare afd across subjects. Is this correct?
Cheers
Chiara
