Both the command line BLAST and the Galaxy Framework at UFRC use the same BLAST databases. We retain two releases of the BLASTDB (blast databases) at a time. The current BLASTDB version is made available to the ncbi_blast tools via the BLASTDB environment variable. Currently provided databases are listed below. If you need a custom database or an out-of-cycle NCBI database update to be added and would like to avoid using up your personal filespace quota please file a Support Request Ticket or contact the UFRC Biological Computing Support. The BLAST databases are updated every three months. However, to ensure reproducibility of the BLAST results within the time frame of an average bioinformatics project two old database releases are kept and can be accessed by setting the "$BLASTDB" variable in the job script or by selecting the appropriate database in the BLAST interface in the Galaxy.

NCBI BLASTDB releases

All databases are full mirrors of NCBI data

  • 202404 - default
  • 202304
  • 202112

BLASTDB location

All databases are located in sub-directories of /data/reference/blast. The default database directory is a symlink to the latest release, but the older releases are still available. Its location is set automatically by the ncbi_blast module via the "$BLASTDB" variable. To override the default database location to perhaps use the older release run 'export BLASTDB=/some/path' either on the command line or in the job script as appropriate. E.g. 'export BLASTDB=/data/reference/blast/201506'. Afterwards, continue calling databases by name without the full path. For example, 'blastx -db nr ...'.
