Summary: The usage of current sequence search tools becomes increasingly slower as databases of protein sequences continue to grow exponentially. Tachyon, a new algorithm that identifies closely related protein sequences ~200 times faster than standard BLAST, circumvents this limitation with a reduced database and oligopeptide matching heuristic.#R##N##R##N#Availability and implementation: The tool is publicly accessible as a webserver at http://tachyon.bii.a-star.edu.sg and can also be accessed programmatically through SOAP.#R##N##R##N#Contact: sebastianms@bii.a-star.edu.sg#R##N##R##N#Supplementary information:Supplementary data are available at the Bioinformatics online.

Tachyon search speeds up retrieval of similar sequences by several orders of magnitude
