The photo legend in “Institutes prepare for pioneering bioinformatics work” (Nature 412, 106; 2001) incorrectly stated that Nadia Rosenthal will lead the mouse biology programme at the European Mouse Mutant Archive (EMMA). The programme is in fact at the European Molecular Biology Laboratory (EMBL) in Monterotondo — EMMA is located on the same campus but is not part of the EMBL.
