BLAST

Overview

BLAST (Basic Local Alignment Search Tool) is a collection of searching programs for biological sequence databases. The program uses the BLAST algorithm (see references below), to compare protein or DNA sequence queries to protein or DNA sequence databases.

Restrictions on Use

There are currently no restrictions on use.

Set Up Procedure

The blast tree is located in /share/apps/supported/htblast including a README, which is recommended reading for new users.

The location of the BLAST data files needs to be stored in the ~/.ncbirc file. There are some datasets in /share/apps/supported/htblast/data. You can gain access to the binaries by loading the bioinformatics module.

Running the Code

Full information is in the README that has been specified above.
