IMHO, it might be desirable to have getaffine and setaffine generate and write matrices suitable for Julia's 1-based indexing. The relevant fields of NIfTI headers are such that they work for 0-based indexing. This would make using these matrices much easier within Julia.

I can understand if you are not interested in making such a change as it might break existing code. Some have also criticised the SPM nifti objects for including this conversion between 0 and 1 indexing.

I have an almost completely functional branch working where I've switched everything to 1 based indexing (including the phase/frequency dimensions). It's almost completely ready to be pushed to master with the exception of some issues with qform.
