piRNAome 2026.1 data files for C. elegans, D. melanogaster, M. musculus, and R. norvegicus. Each species provides six files: piRNA FASTA, piRNA GTF (genomic loci), cluster GTF (known + de novo), ID aliases, families + annotation, and SNV results. Human (GRCh38) data are on the main portal: pirnaome.org/download ↗. See README.md for formats and conventions.
