In the version of this article initially published, in Fig. 1f, the color keys for “Left (–90 kb)” and “Right (+90 kb),” currently appearing as dark grey and light grey, respectively, were incorrectly swapped. In Fig. 3d, the data presented were inadvertent duplicates of Fig. 3j. Figures 1f and 3d have now been amended in the HTML and PDF versions of the article.
