[Neuroimaging] Two (beginner) questions for DiPy

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?

Thanks a lot!
