Correction to: Nature Machine Intelligence https://doi.org/10.1038/s42256-019-0049-9, published online 13 May 2019.

In the version of this Article originally published, the labels in Fig. 4c,d, and Fig. 6b were not aligned with the data points. The H and D in ‘HRD’ (Fig. 4c,d) and the second D in ‘MDKKYSIGLDIGTN’ should have been directly below the negative peaks. In Fig. 7a, the citations were incorrect: ‘Ref. 41’ should have been ‘Ref. 42’, and ‘Ref. 39’ should have been ‘Ref. 40’. To make the citation style in Fig. 7a consistent, ‘Dong et al., Nature 2017’ under ‘G38A’ has been changed to ‘Ref. 41’. The reference to Dong et al. under ‘E70A’ was incorrect; it should have been ‘Ref. 40’. The citation for ‘I80A’ was missing; it should have been ‘Ref. 40’.
