The wwPDB responds to the article by Jaskolski [(2013), Acta Cryst. D69, 1865-1866] .
In his paper On the propagation of errors (2013), Jaskolski makes several points about the annotation of ligands in the Protein Data Bank. Since 2007, the Worldwide Protein Data Bank (wwPDB) has undertaken several rounds of remediation of the entire PDB archive in an effort to improve the quality, integrity and consistency of the data. This is an ongoing effort and we will take the issues raised in this paper into account when we prioritize future remediation efforts.
Our response to the specific issues raised is as follows.
