A revised proof of the metric properties of optimally superimposed vector sets.
A revised proof is given that the root-mean-square deviation between more than two vector sets after optimal superposition induces a metric. This corrects an error in a previous manuscript [Kaindl & Steipe (1997). Acta Cryst. A53, 809].
