Gapped BLAST and PSI-BLAST: a new generation of protein database search programs.

BLAST program is widely used tool to find protein and DNA databases for sequence similarities. For protein comparisons, various definitions, algorithmic and statistical improvements described here allows the BLAST program execution time will decrease substantially while increasing their sensitivity to weak similarity. New criteria to trigger the expansion of word hits, combined with new heuristics […]
