affine does not exist in nibabel 1.3, it's get_affine, which is deprecated

I tried to run the example, but it assumes the nibabel 2.0 command for the affine (without expliciting the version requirements in the install). The old 1.0 way of doing it is get_affine, but that is deprecated according to http://nipy.org/nibabel/reference/nibabel.spatialimages.html

So, as a workaround, I suggest either

• putting nibabel 2.0 as a dependency
• checking for nibabel version with nibabel.version and use affine for 2.0 (like it is currently doing) and use get_affine for nibabel 1.

Second option won't force people to upgrade, but requires some code edit.

Thanks @samuelstjean for testing! I'm really new in Python, but I guess now the issue should be fixed.

Yes, it works now, thanks.
