Did you also change the origin of the ROI image? If you only changed the
positioning of the T1 then it will no longer be in alignment with data that
it was previously aligned with. Note also that not all visualisation
packages will show this mis-alignment. Only those that correctly deal with
NIFTI headers will show it.
