BLAST+ executables

BLAST+ is a suite of command-line tools to run BLAST. For details, please see the BLAST+ user manual, the BLAST Help manual, the BLAST releases notes, and the article in BMC Bioinformatics (PubMed link). BLAST+ is the most current version of BLAST and is the only supported version.

Installers and source code are available from ftp://ftp.ncbi.nlm.nih.gov/blast/executables/blast+/LATEST/ .

The BLAST+ suite is the currently supported package. The older C toolkit executables are no longer supported.
