Dear MRtrixer ,
I have a question about peak extraction of FODs.
Using amp2sh and then sh2peaks command I can extract the peaks of signal. is it correct ?
But if I want to extract the peaks of FODs map. Is it right to use FODs as an input of sh2peaks ?
Yes, that’s correct:
sh2peaks on the FOD image (which is stored as SH coefficients) will simply extract the peaks of the FOD. Alternatively, you could also use a combination of
fixel2voxel to get the directions of the segmented FOD lobes (this is what’s done within
dwi2response, for instance).
Thanks for your explanation
