Correction to: Nature https://doi.org/10.1038/s41586-018-0356-z Published online 25 July 2018

During the publication process, the authors mistakenly included the wrong image for Fig. 3c. The correct Fig. 3c is shown as Fig. 1 below. The error is in presentation and makes no material difference to the scientific conclusions. The values shown in the legend for Fig. 3c and in the supporting information (Table S8) remain correct. We would like to acknowledge the anonymous scientist who pointed out the error.
