Complete length H5N6 Influenza A Virus Genomes: Host Adaptation Signatures and Evolutionary Metrics n=6768

This dataset includes 6,768 complete H5N6 influenza A virus sequences from NCBI, processed using local Python and Biopython scripts. Sequences underwent completeness filtering, MAFFT alignment (<code>--parttree --retree 1</code>), and custom trimming. Codon usage metrics (ENc, CAI for human/avian hosts, GC3, RSCU, CPB, PR2) were calculated per sequence. Year and country metadata were extracted from FASTA headers. Dataset contains aligned FASTA, codon metrics CSV, QC reports, and plots for temporal, geographic, and codon adaptation analysis.Data processed by [e-mail]
