NAME¶
ncbi-blast+ - NCBI command tools for BLAST+
DESCRIPTION¶
The NCBI BLAST+ is a group of tools for basic alignment search. BLAST+
is a rewrite of BLAST with new features and performance improvements. BLAST+
commands differ from original BLAST. For BLAST users, one should read
the BLAST USERS paragraph.
CONFIGURATION¶
BLAST+ uses the BLASTDB environment variable to get default db directory. It is
possible to update the file /etc/ncbi/.ncbirc to add the following:
[BLAST] BLASTDB=/var/lib/ncbi-blast+/db
BLAST USERS¶
The easiest way to get started using these command line applications is
by means of the legacy_blast.pl PERL script which is bundled along with
the BLAST+ applications. To utilize this script, simply prefix it to the
invocation of the C toolkit
BLAST command line application and append the --path option pointing to the
installation directory of the BLAST+ applications. For example, instead of
using
blastall -i query -d nr -o blast.out use legacy_blast.pl
blastall -i query -d nr -o blast.out --path /usr/bin
