Thanks, this looks great! I have a few suggestions.

Again, something like

desc='Scale factors to rescale the image by in each dimension'

Just as a heads up, you can test your doctests locally with:

pytest --doctest-modules nipype/interfaces/mrtrix3/utils.py

I think you're going to need to create new interfaces for each of the three examples, or you're going to get bitten by the xor.

Great catch! I was also missing a coma
