*Correspondence e-mail: boris.steipe@utoronto.ca
A technical error invalidates the proof that the optimal root-mean-square deviation of vector sets induces a metric given in Kaindl & Steipe [Acta Cryst. (1997![[Kaindl, K. & Steipe, B. (1997). Acta Cryst. A53, 809.]](../../../../../../logos/arrows/a_arr.gif "Kaindl, K. & Steipe, B. (1997). Acta Cryst. A53, 809.")
), A53, 809]. Nevertheless, the conclusions are correct and a revised proof is given in Steipe [Acta Cryst. (2002), A58, 506].
Keywords: metric spaces; root-mean-square deviation; superposition.
