  2. This is a subset of the predictions generated by SynFPS. SS refers to Sequence Similarity: N indicates there is no significance in sequence similarity between the target gene (first column) and any of the corresponding genes in the supporting phages (second last column) within the same cluster; Y indicates at least one of the corresponding genes show significant similarity. BLAST-P with Blosum45 has been used to test for similarity significance.
