Figure 2From: PhiSiGns: an online tool to identify signature genes in phages and design PCR primers for examining phage diversityWeb interface for the identification of signature genes. The interface shows 1) the options to limit the display of available phage genomes, 2) a list of phage genomes meeting the selection criteria, 3) a list of the user-selected phage genomes from step (2) for signature gene identification and primer design, 4) the BLAST E-value cut-off for similarity searches, and 5) the BLAST alignment coverage cut-off for similarity searches.
