The distribution of the number of LCBs shared by the strains. Before being filtered, 528 and 618 LCBs were shared by 2 and 36 strains, respectively (orange). After being filtered using a cutoff of 1.01, 412 and 35 LCBs shared by 2 and 36 strains, respectively, remained (blue). A cutoff value of 1.01 means that the length of the gaps in the LCBs is less than 1% of the length of the non-gap regions.
