This 5d thing is caused by AFNI, right?

If you are using pynifti you can do something like this (just a sketch):

>>> img = NiftiImage('something_from_afni.nii.gz')
>>> img.data = img.data.squeeze()
>>> ds = NiftiDataset(samples=img, mask='from_somewhere.nii.gz', ...)

Something similar should work with NiBabel too.
