H5N2 Influenza A Virus Genomes: Codon Bias and Epidemiological Metadata n=12,765

This dataset comprises 12,765 complete H5N2 influenza A virus sequences from NCBI, processed via local bioinformatics pipelines. Sequences were validated as full-length, aligned using MAFFT (--parttree --retree 1), and trimmed. Per-sequence codon usage analysis includes ENc, CAI (human/avian), GC3, RSCU, CPB, and PR2.
Metadata on collection year and country were parsed from headers. Delivered with aligned FASTA, codon metrics CSV, QC summaries, and visualizations of temporal, geographic, and evolutionary trends.
