In the paper `A strict solution for the optimal superimposition of protein structures' by Chuanbo Chen & Qishen Li [Acta Cryst. (2004), A60, 201–203], we claimed that existing methods for the optimal superimposition of two point sets, requiring the precondition of coincident centroids, are mathematically not strict. It has been brought to our attention that this claim is erroneous. We therefore retract the publication.
Keywords: bioinformatics; protein structure; optimal superimposition.
