Extraction of infrequent simple motifs from a finite set of sequences using a lattice structure.

In this paper we present a method for finding infrequent simple motifs in a finite set of sequences. The method uses a lattice structure and minimal forbidden patterns. It is based on a method for solving the Simple Motif Problem and has the potential to discover new patents in biological macromolecules. Indeed, the extracted motifs can help biologists to learn about the biological functions of these macromolecules and, consequently, can help them to understand the mechanisms of the biological processes in which these sequences are involved.
