This example screenshot displays the Database Engineer, which is used for scanning for child nodes, creating custom databases and distributing existing databases. Within the same interface is the BLAST engine, which is used for executing inputting query sequences, choosing BLAST parameters, and executing BLAST jobs. Also available is the ability to control child nodes during BLAST jobs. Lastly, the user has the option of resuming a failed BLAST.
