Maybe we could be as clear (and not hit line length limits) by just adding slice_encoding_direction=metadata.get('SliceEncodingDirection', 'k') to the TShift() call.

OK. I have tested the previous version and this looks good

  • same list order, different direction gives different results (as expected)
  • flipped list, flipped direction gives same results (as expected)
  • no direction vs "k" gives same results (as expected)


copy_xform = pe.Node(CopyXForm(), name='copy_xform', mem_gb=0.1)
