Metagenomic analysis reveals extensive diversity and functional potential in the poultry gut DNA virome

Data release of the AvianViromeDB catalog for the study "Metagenomic analysis reveals extensive diversity and functional potential in the poultry gut DNA virome". The catalog contains 61,608 vOTUs from 2,658 public avian gut metagenomic source records, with 2,290,347 representative proteins. Files vOTUs.fasta.gz: representative sequence of each vOTU vOTU_proteins.faa.gz: proteins predicted from the representative sequences vOTU_annotation.tsv.gz: CheckV quality, taxonomy, lifestyle, vConTACT3 cluster and bird-source fields of each vOTU vOTU_prokyriotic_hosts.tsv.gz: iPHoP prokaryotic host predictions gene_annotations.tar.gz: auxiliary metabolic gene annotations (DRAM-v, VIBRANT) and antibiotic resistance gene annotations source_inventory.tsv.gz: the 2,658 source records with run, BioSample and BioProject accessions vOTU_source_members.tsv.gz and vOTU_bird_sources.tsv.gz: member contigs and bird-source categories of each vOTU legacy_bird_source_annotations.tsv.gz: historical host and prevalence fields kept for provenance AvianViromeDB.sqlite: all tables in one SQLite database db_description.txt: field definitions manifest.json: checksums and validation counts supplementary tables.zip: Supplementary Tables S1–S15 of the revised manuscript Changes from the version of 2026-01-23: contig_repid names the exported representative of each vOTU and original_representative_id links the archived network annotations (2,757 vOTUs); taxonomy rank fields report unassigned where the archived classifier output has a placeholder label, and archived_lineage keeps the archived labels; reviewed source metadata are provided in separate tables.
