In the version of this article from the January 8, 2020 issue of Cell Host & Microbe, originally published online on December 17, 2019, the first tab of Table S5 contained shortened sequences that did not properly represent longer elements due to a limitation of Microsoft Excel. The authors have provided a new table in which the original “repr_seq” column data has been replaced with links to a CSV in a github repository containing the full sequences. To access the full sequences, this CSV should not be opened in Microsoft Excel, but can be analyzed with separate software. These corrections were made online on September 25, 2020. The authors sincerely regret this error.
