CHPC - Research Computing and Data Support for the University
In addition to deploying and operating high performance computational resources and providing advanced user support and training, CHPC serves as an expert team to broadly support the increasingly diverse research computing and data needs on campus. These needs include support for big data, big data movement, data analytics, security, virtual machines, Windows science application servers, protected environments for data mining and analysis of protected health information, and advanced networking.
If you are new to CHPC, the best place to start to get more information on CHPC resources and policies is our Getting Started page.

Nanopore sequencing reveals rapid evolution of poxvirus genome structure driven by host-pathogen conflict
By Tom Sasani, Kelsey Rogers-Cone, Ryan Layer, Nels Elde & Aaron R. Quinlan
Quinlan Lab, Department of Human Genomics and USTAR Center for Genetic Discovery, University of Utah
Vaccinia virus (VACV) encodes two host-range factors, E3L, and K3L, that each disrupt key antiviral host defenses. In the absence of E3L, VACV has been shown to rapidly adapt by duplicating K3L in tandem arrays, which confers a significant increase in fitness. Additionally, viruses accumulate H47R mutations within K3L, which provides an added fitness benefit. In order to investigate the relationship between K3L copy number amplification and H47R allele fixation, we sequenced VACV populations with the Oxford Nanopore (ONT) single-molecule platform. We discovered that H47R progressively accumulates within arrays of the duplicated K3L gene, and uncovered some of the interplay between allelic diversity and structural variation during viral evolution.
