Example chiral errors in H3 model from PZ07 (top) and H4 model from PZ06 (bottom). (Top left) C3′ atom in U82 with correct chiral center. (Top right) U15 with incorrect chiral inversion at carbon atom C3′, actually changing a ribose to a xylose moiety. (Bottom left) A2 with correct chirality at C4′. (Bottom right) G82 with incorrect chirality at C4′.
