Alignment fragment. Fragment of an alignment of 31 Staphyloccocus aureus phage genomes that covers the segments between their terminase gene [module Te] and their tape measure gene [module Ta]. Module P is the anchor module corresponding to the portal gene. In a column, two cells that have the same color (or number) are highly similar. Empty sequences are designated by 0, and colored by their neighboring cells if both have the same color. Cells with variants that are unique are not colored.
