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

Bioinformatics. 2012 Jun 15;28(12):1645-6. doi: 10.1093/bioinformatics/bts197. Epub 2012 Apr 23.


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.

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.
