Protein Fragment Motif Finder (PFMFind) is a system that enables e cient discovery of relationships between short fragments of protein sequences using similarity search. It supports queries based on amino acid similarity matrices and position specific score matrices (PSSMs) obtained through an iterative procedure. PSSM construction is customisable through plugins written in Python. PFMFind consists of a GUI client, an index for fast similarity search and a relational database for storing search results and sequence annotations. It is written mostly in Python. The components of PFMFind communicate through TCP/IP sockets and can be located on different physical machines. PFMFind is freely available for download (under a GPL licence) from http://pfmfind.stojmirovic.org.
