Correction to: Nature Methods, published online 10 June 2022.

In the version of this article originally published, the illustration in the top-left plot of the “Long-read technologies” section of Fig. 1a was inadvertently duplicated in the plot, while the lower red rectangles alongside “Human_GRCh38” in Fig. 2a were missing. The duplicate illustration has been removed and the rectangles have been restored in the HTML and PDF versions of the article.
