Complete H5N5 Influenza A Virus Genomes: Codon Adaptation and Metadata

This dataset includes 446 complete H5N5 influenza A virus sequences from NCBI, processed via local bioinformatics pipelines. Sequences were filtered, aligned with MAFFT (--auto), and trimmed. Codon usage metrics (ENc, CAI for human/avian hosts, GC3, RSCU, CPB, PR2) were computed per sequence. Year and country metadata were parsed from headers. Package contains aligned FASTA, codon metrics CSV, QC summaries, and visualizations.<br>CODON USAGE SUMMARY: H5N5========================================Total sequences: 446<b>Valid CDS</b>: 48 (10.8%)Valid CAI: 48 (10.8%)<br>METRIC STATISTICS (Mean ± SD): ENc (Effective Number of Codons): 35.114 ± 2.216 CPB (Codon Pair Bias): 4.912 ± 0.897 CAI_human: 3.419 ± 0.116 CAI_avian: 3.438 ± 0.119 GC3: 0.446 ± 0.035 PR2_A (A3/(A3+T3)): 0.576 ± 0.044 PR2_G (G3/(G3+C3)): 0.528 ± 0.041<br>INTERPRETATION: → Strong codon usage bias (ENc &lt; 40) → Similar adaptation to human/avian hosts<br>Data processed by: [e-mail]
