Overview

BLAST: In bioinformatics, BLAST is an algorithm and program for comparing primary biological sequence information, such as the amino-acid sequences of proteins or the nucleotides of DNA and/or RNA sequences.

• User Manual

Using

Use the module name blast-plus to discover versions available and to load the application.

Multicore

Some of the suite of tools can be used across multicores. Look at the help for each command to identify what it can do. For example look at blastp -help for the -num_threads option.

Blast Database

• ARCC has a version of the related BLAST database installed on Teton and WilidIirs that is configured so that blast knows where to look for it (so you don't have to worry about this).

• Due to the reasonably dynamic nature of this database, ARCC does have a method to update this database on request.

Here is a list of the current databases on the various clusters:

Version: 2.6.10

Since the last update of the database, version 2.6.0 is no longer compatible with this database. If you try running blastp with this version, you will see the following error message:

BLAST Database error: Error: Not a valid version 4 database.
