Blast+

Description

BLAST+ is a new suite of BLAST tools that utilizes the NCBI C++ Toolkit. The BLAST+ applications have a number of performance and feature improvements over the legacy BLAST applications

We maintain a local copy of several Blast databases – see the /storage/projects/BlastDB directory. All available databases are described at NCBI web. We mirror all of them. Last update of the offline copy is october 2016. If you need to update DBs or to add some new, please contact the user support meta@cesnet.cz. Databases are ready to use. For your blastn/blastp/tblastx etc. job, use only database base name e.g. nt, nr, wgs, refseq_genomic (-db option).

Upcoming modulesystem change alert!

Due to large number of applications and their versions it is not practical to keep them explicitly listed at our wiki pages. Therefore an upgrade of modulefiles is underway. A feature of this upgrade will be the existence of default module for every application. This default choice does not need version number and it will load some (usually latest) version.

You can test the new version now by adding a line

source /cvmfs/software.metacentrum.cz/modulefiles/5.1.0/loadmodules

to your script before loading a module. Then, you can list all versions of blast+ and load default version of blast+ as

module avail blast+/ # list available modules
module load blast+   # load (default) module

If you wish to keep up to the current system, it is still possible. Simply list all modules by

module avail blast+

and choose explicit version you want to use.
