"Blast" is composed of a set of programs. Here is the list of the man pages for the utilities available on the wbe.

•     blastall - given sequences in FASTA format, find similar sequences in a BLAST database

•     filtering - a process by which low complexity regions are masked from query sequences.
•     profile - A position-specific scoring matrix (PSSM) created by position-specific iterated BLAST (psiblast).

•     FASTA - Originally a protein alignment algorith, in this context FASTA refers to an uncompressed text representation of nucleotide or protein sequence data.

•     BLAST database - A set of protein or nucleotide sequences in a format suitable for efficient searching.
•     RPSBLAST database - A set of profiles in a format suitable for efficient searching.
