hsa_piRNA.fasta.gz
All 10,033,305 piRNA sequences. FASTA headers carry the accession, display ID, and length.

hsa_piRNA.gtf.gz
Genomic loci of 9,942,083 placed piRNAs (primary locus per piRNA; entries with no genomic match are excluded). 1-based GTF; attributes carry the piRNA / locus / family / cluster accessions and genomic context.

hsa_piRNA_clusters.gtf
9,768 cluster intervals: 1,501 sourced intervals and 8,267 PICB-detected intervals passing the post-PICB matched random-placement accepted-piRNA-locus enrichment threshold at FDR ≤0.05. PICB intervals above this threshold remain in the release SQLite database but are not included in this website download.

hsa_id_aliases.tsv.gz
11,315,648 source-database identifier aliases per piRNA (piRBase, piRNAdb, NCBI, piRNABank, piRNAQuest, piOxiDB, proTRAC).

hsa_families_annotation.tsv.gz
Family-assignment records with annotation (dominant TE class/family/name, gene region, anchor / root-locus context). The public catalogue contains 1,231,773 piRNA families with at least two members. Singleton sequence records are retained in this file for traceability but are not counted as families.

hsa_snv_results.tsv.gz
4,952,525 locus-level SNVs with dbSNP / ClinVar / COSMIC / REDIportal cross-references, read-oriented change, 3′-terminal tailing flag, and interpretation.

hsa_family_overlaps.tsv.gz
785,144 piRNA–piRNA family overlaps (overlapping / adjacent locus pairs on the same strand). Each row gives both partners' piRNA / locus / family accessions, genomic coordinates, sequences, locus status, and the gap (nt).
