Correction to: Nature Reviews Methods Primers https://doi.org/10.1038/s43586-021-00038-x, published online 3 June 2021.

In the version of this article initially published, there was an error in the second displayed equation in the Results subsection “Single-molecule localization”. The equation now reading

$${\sigma }_{loc}\ge \sqrt{\left(\frac{{\sigma }_{0}^{2}+{a}^{2}/12}{N}\right)\left(\frac{16}{9}+\frac{8\pi ({\sigma }_{0}^{2}+{a}^{2}/12){b}^{2}}{N{a}^{2}}\right)}$$

appeared originally as

$${\sigma }_{loc}\ge \sqrt{\left(\frac{{\sigma }_{0}^{2}+{a}^{2}/12}{N}\right)\left(\frac{16}{9}+\frac{8\pi {\sigma }_{0}^{2}{b}^{2}}{{a}^{2}{N}^{2}}\right)}$$

The equation has been revised in the HTML and PDF versions of the article.
