The heatmap showing percentage intergenomic sequence similarities (upper right half) and alignment genome fraction and genome length ratios (lower left half) for E. coli O177 phages and their closely related four Escherichia phages computed using VIRIDIC. The horizontal and vertical coordinates depict the corresponding phages GenBank accession number and the E. coli O177 phages in this study are indicated by the red asterisk (*) symbol next to their accession numbers accession number.
