@paquiteau would adding these steps be useful for an example, or should they go into a function/class within patch-denoising?

Well, this is already done in the load_complex_nifti function, which is what people would use in practice. I don't think it's needed to refactor that.

Are you referring to combining the complex-valued data or the phase filtering and g-factor map creation? load_complex_nifti doesn't do the latter. Also, it doesn't rescale the phase data to -pi to pi, right? So this example definitely needs to separately rescale the data.

This is just a draft of an example that applies NORDIC to complex-valued data with noise volumes.
