Correction to: Nature Methods https://doi.org/10.1038/s41592-019-0364-4, published online 8 April 2019

In the version of this paper originally published, Figure 4a contained errors that were introduced during typesetting. The bottom 11° ThunderSTORM image is an xz view but was incorrectly labeled as xy, and the low x-axis value in the four line profiles was incorrectly set as –60 instead of –50. These errors have been corrected in the PDF and HTML versions of the paper.
