In the version of this article initially published, labels reading “5hmC gain” were incorrectly included below the plots in Figure 6e, and the plot at right was mislabeled above (as “loss”). The plot at left should have a single label above reading “5hmC loss” and the plot at right should have a single label above reading “5hmC gain.” The error has been corrected in the HTML and PDF versions of the article.
