Hi Benedikt,

> Dear all,
> first of all thank you very much for making DiPy publicly available.
> I am new to Python and diffusion imaging (I have worked before with R and
> genetics), and have two (hopefully easy) questions:
> 1) As input, I have a 4D nifti image with my B0 and B1000 images stacked.
> How can I run an affine registration (for motion / eddy correction) on this
> stack, using the first B0 image as fixed image and the remaining images
> (one after another) as moving images? Or do I have to split the stack first?
> 2) How do I rotate the B-matrix after registration?

This function will do that:



> Thanks a lot!
