This protocol\u00a0outlines the quality control analysis measuring the percent relative abundance of 16S rRNA levels in the virome and whole metagenome, as well as the number of virome sequences mapping to the whole metagenome, and vice versa. These measures are used to validate the quality of the sequence datasets. Based on the methods from the following publication:Hannigan, Geoffrey D., et al. "The Human Skin Double-Stranded DNA Virome: Topographical and Temporal Diversity, Genetic Enrichment, and Dynamic Associations with the Host Microbiome."\u00a0mBio\u00a06.5 (2015): e01578-15.
