Unfortunately, DWIConvert has some crash modes which do not produce informative error messages due to exception handling issues. My guess is that something about your files does not correspond to DWIConvert’s expectation, and it crashes. If you can reproduce your workflow on one of these [public datasets](https://discourse.slicer.org/t/not-working-dwi-component/4793/3?u=ihnorton), and then share the resulting nrrd file with me, then I can take a look.
