Save transformed data

I have tried “hardening” the transformation and saving it. The saved images are in their native coordinate spaces and orientations. Is there a way to save them all regridded to the same 3D matrix?

Sorry if this is an obvious question, but I can’t seem to find how to do this in the documentation.

The data is all registered and ready to go.

I have been meaning to learn Python, but don’t have time today to jump in.

Thanks,
Nathan
