Basic Local Alignment Search Tool iconBasic Local Alignment Search Tool 2.2.26

A set of similarity search programs.
Basic Local Alignment Search Tool is in short BLAST is a set of similarity search programs designed to explore all of the available sequence databases regardless of whether the query is protein or DNA.

It uses a heuristic algorithm which seeks local as opposed to global alignments, and is therefore able to detect relationships among sequences which share only isolated regions of similarity.

It can be run locally as a full executable, and can be used to run BLAST searches against private, local databases, or downloaded copies of the NCBI databases. It runs on Mac OS, Win32, LINUX, Solaris, IBM AIX, SGI, Compaq OSF, and HP- UX systems.
