PINALOG is a protein-protein interaction(PPI) network alignment method aiming to map similar parts of PPI networks in terms of protein similarity (by both sequence and function) and the local network similarity. PINALOG incorporates not only sequence similarity and topological similarity of proteins in the equivalencing process but also uses the function similarity of protein pairs.
