Erratum: Corrigendum: Accurate macromolecular structures using minimal measurements from X-ray free-electron lasers

Nat. Methods 11, 545–548 (2014); published online 16 March 2014; corrected after print 3 June 2015 In the version of this article initially published, the authors claimed that with the tool cctbx.xfel, weak diffraction signals can be measured using fewer crystal specimens than are needed for the previously available program CrystFEL.
