The Integrated Microbial Genomes (IMG) system is a complex data management system which integrates the Joint Genome Institute's microbial genome data with publicly available microbial genome data, and thus provides a powerful comparative context for microbial genome analysis.
One of the more computationally demanding steps in the IMG pipeline involves comparing newly sequenced genes against existing reference genes. BLAST (Basic Local Alignment Search Tool) is used to perform this comparison. This requires comparing over 12 million genes against nearly 7 million genes. This work is typically performed on local clusters with around 200 cores and takes around two weeks to complete. Using the Franklin system can reduce turnaround time to one day or less.
The request for NISE time is finish porting the entire IMG pipeline to Franklin and to prepare a computational framework for upcoming sequencers that will quickly overwhelm the computational resources at sequencing centers like JGI.
