Assessing the Quality of Whole Genome Alignments in Bacteria

Figure 1

A schematic illustration of a genome mapping result. Each genome (illustrated as a straight line) is broken into segments or fragments (the labeled rectangular blocks), and each segment is mapped to a corresponding one in the other genome. The breakage of the genome into segments is referred to as segmentation. Segments with an identical label but different signs have reversed orientation. Note that a segmentation may leave regions outside of the blocks. Those regions are considered segmental insertions/deletions and are not included in the mapping between the genomes.
