MoTeX: A word-based HPC tool for MoTif extraction

Motivation: Identifying repeated factors that occur in a string of letters or common factors that occur in a set of strings represents an important task in computer science and biology. Such patterns are called motifs, and the process of identifying them is called motif extraction. In biology, motifs may correspond to functional elements in DNA, RNA, or protein molecules. Motifs may also correspond to whole loci whose sequences are highly similar because of recent duplication (e.g., transposable elements or recently duplicated genes). A DNA motif is a nucleic acid sequence that has a specific biological function, for instance encoding the DNA binding sites for a regulatory protein (transcription factor).
