Virome and whole metagenomic sequencing reads were assembled and filtered for viral properties, resulting in 2,511 viral contigs (VCs) and 3,122 metagenome-derived viral contigs (mVCs). The source read counts represent host and spike-in removed reads that were subjected to quality filtering and trimming. Contigs were annotated using Demovir.
