Creation and Analysis of a Virome: Using CRISPR Spacers

Methods Mol Biol. 2015;1311:307-16. doi: 10.1007/978-1-4939-2687-9_20.


Advances in sequencing technology have allowed for the study of complex and previously unexplored microbial and viral populations; however, linking host-phage partners using in silico techniques has been challenging. Here, we describe the flow-through for creation of a virome, and its subsequent analysis with the viral assembly and analysis module "Viritas," which we have recently developed. This module allows for binning of contigs based on tetranucleotide frequencies, putative phage-host partner identification by CRISPR spacer matching, and identification of ORFs.
