Are you sure this makes sense? Per-residue RMSD values are sensitive to domain shifts because they are influenced by global rotation/translation and don't really represent per-residue structural similarity. Of course this depends on what you want to achieve - but you may be better of using a rotation/translation invariant metric based on internal coordinates: distance differences or torsion angle differences.
