This is very possible with using the mask. It can be better to include
some background.
Could you email me this pair of images and masks? I am very interested
to think about any way to improve upon this.
Thanks

problem with you. I want to narrow down the problem a little bit.
Could you try doing affine registration without using masks first?
Thanks Brian and Gang for the hint regarding the mask. Indeed the major
offset was gone after rerunning without a mask. However, alignment was
still poor and processing time increased to an hour :-(. We ran at with
a dilated mask afterwards (gaussian kernel 8mm FWHM) that seems to yield
optimal results -- nicely aligned.
It might be worth adding this advice to the documentation.
Thanks again,
Michael
