In the Editorial 'The data deluge' (August 2012) published online and in print, the reported number of movies produced by the Mitocheck project was incorrect. The correct text is: “On a more modest scale, the 1000 Genomes Project, a data set of human genetic variation, has already generated about 200 terabytes of data, and MitoCheck, a systematic genome-wide analysis of about 21,000 human genes, generated about 190,000 movies representing a total of 24 terabytes.”

This was corrected online on 17th October 2012.
