Correction to: Nature Chemical Biology, published online 13 July 2020

In the version of this article originally published, there were errors in Fig. 4 and Extended Data Figs. 5 and 7. In Fig. 4f, labels “+ aTc” and “− atc” were on the wrong sides. “+ aTc” should be placed over the blue bar on the right-hand column, and “− aTc” should be on the left. In Extended Data Fig. 5b, the colormap accompanying the nonlinear ultrasound image was blank. Additionally, the label "ASGWT" on the left should be "ARGWT", and the orange and blue overbar colors should be swapped, with orange on the right and blue on the left. In Extended Data Fig. 7, the colormaps accompanying the nonlinear ultrasound images in b and c were blank, and the significance asterisks above the nonlinear data in d and e were shown as crossed squares. The errors have been corrected in the HTML and PDF versions of the paper.
