BLAST Version 2.2.4 Released: Web BLAST Linkouts

The latest version of the BLAST programs, version 2.2.4, supports discontiguous word matching in MegaBLAST. In addition, stand-alone BLAST supports an out-of-frame gapping option for blastx searches, allowing one or two bases, rather than the usual in-frame multiples of three, to be inserted or deleted from an alignment. The expect values are still calculated assuming in-frame gapping.

Fastacmd, a program to retrieve sequences from a formatted BLAST database, can now retrieve partial sequences (using the -L option) and print taxonomic information for a sequence.

BLAST version 2.2.4 is available at ftp://ftp.ncbi.nih.gov/blast/executables/.
