BLAST Ring Image Generator (BRIG)

Installing BRIG

BRIG will run from wherever the program is unzipped. No installation required, however, users will require NCBI BLAST+ or BLAST legacy, and Java 1.6 or greater to be installed.

To run BRIG users need to:

Users who wish to run BRIG from the command-line need to:

  • Navigate to the unpacked BRIG folder in a command-line interface (terminal, console, command prompt).
  • Run ‘java -Xmx1500M -jar BRIG.jar’. Where -Xmx specifies the amount of memory allocated to BRIG.

Installing BLAST

The latest version of BLAST+ can be downloaded from:

BLAST+ offers a number of improvements on the original BLAST implementation and comes as a bundled installer, which will walk users through the installation process. Please read the published paper on BLAST+: Camacho, C., G. Coulouris, et al. (2009). ‘BLAST+: architecture and applications.’ BMC Bioinformatics 10(1): 421

The latest version of BLAST legacy can be downloaded from:

BLAST legacy comes as a compressed package, which will unzip the BLAST binaries where ever the package is. We advise users to first create a BLAST directory (in either the home or applications directory), copy the downloaded BLAST package to that directory and unzip the package.

BRIG supports both BLAST+ & BLAST Legacy. If BRIG cannot find BLAST it will prompt users at runtime. Users can specify the location of their BLAST installation in the BRIG options menu which is: Main window > Preferences > BRIG options. N.B: If BOTH BLAST+ and legacy versions are in the same location, BRIG will prefer BLAST+
