Hi all, I am using this old thread because it seems very similar to my question. I just applied dwidenoise on a multishell dataset. However, the DWI residuals output with the -noise look like it has some structure, and the brain emerges quite clearly. Here is a screenshot. I can upload the nifti somehwere if necessary (it doesn’t get uploaded here).
Any idea if this kind of noise residuals are normal of there is too much structure in the noise.
Here are the bvalues for this dataset:
