Some of the most common biological sequence databases are available on the HPC for you to use with tools like BLAST. Below you can find the list of them, their location on the system, and the last time they were updated.
We endeavor to keep this list updated as the One True List™.

Tools like BLAST use the
BLASTDB environment variable to find the location of the system's BLAST databases. ILRI's BLAST environment modules like
blast/2.10.0+ automatically set this variable when you load the module.
If you are using different software you will need to set the variable manually, for example:
$ export BLASTDB=$BLASTDB:/export/data/bio/ncbi/blast/db/v5 $ blastn -db nt -query file.seq -out blast.out
$ module load blast/2.10.0+ $ blastdbcmd -info -db nt | grep Date
