Hi all,

I am trying to use the Denoising feature of DTIPrep, which uses a Rician LMMSE Filter from 3DSlicer. However, I cannot find the path for this tool, and I can’t seem to find the answer online on this forum or on the documentation ([https://www.slicer.org/wiki/Documentation/4.6/Modules/DWIRicianLMMSEFilter](https://www.slicer.org/wiki/Documentation/4.6/Modules/DWIRicianLMMSEFilter)). [This](https://discourse.slicer.org/t/stationary-rician-noise-removal-in-dwi/1989) relevant forum post also remains unanswered. I am using Slicer 4.6.2.

I would appreciate any guidance!

Thank you in advance!
