Contracted vertices. A example of a contracted vertex (top) and its expanded graph (bottom) in the alignment of four S. aureus bacteriophages. The length of the vertex is 169 nucleotides, and the percentage of identity is 98 %. In the expanded graph, there are two single nucleotide mutations that account for the 98 % identity
