Oh,

you’re right. I has managed to make it’s way into the release already then ;-)

So, that would be the way to do it. Make sure that you have duplicated all diffusion directions with opposing PE-directions and use —resamp=lsr.

When the pipeline for the HCP was finalised we didn’t yet have the lsr option, so the HCP data is actually resampled with the jac option and then simply averaged.
