Both are based on Rician noise

I have some questions concerning denoising
procedure in DTIPrep. Denoise is one of good practice. However, I
found there is no difference of the excluded gradients between with
and without denoising procedure.
1. I noticed there is *_DenoiseInput.nrrd file created. I wonder whether and how this denoised file is linked to the DTIPrep output.
2. Is Rician noise removal the same as smoothing in DTIPrep?
