blastall is the old program developed and distributed by the NCBI for running blast searches. The NCBI recommends that people start using the programs of the blast+ package instead. Having said that, most documentation currently available still refers to blastall and the programs distributed with it.

Also, typing man blastall on your Bio-Linux machine will bring up useful information about blastall and other programs distributed with it.

The programs distributed with blastall include:

• bl2seq
• blast2
• blastall
• blastcl3
• blastclust
• blastpgp
• copymat
• fastacmd
• formatdb
• formatrpsdb
• impala
• makemat

The man pages for these provide further details.
