H5N4 Influenza A Virus Genomes: Codon Bias and Metadata

This dataset includes <b>54</b> complete <b>H5N4 influenza A virus sequences</b>, processed using local scripts. Sequences were validated, aligned with MAFFT (--auto), and trimmed. Per-sequence codon metrics (ENc, CAI for human/avian hosts, GC3, RSCU, CPB, PR2) were computed. Year and country metadata were extracted from FASTA headers. Package contains aligned FASTA, codon metrics CSV, QC reports, and analytical plots.Processed by [e-mail]

本数据集包含**54条**完整的**H5N4甲型流感病毒序列（H5N4 influenza A virus sequences）**，通过本地脚本完成处理。所有序列均经过验证，采用MAFFT软件（参数--auto）进行多序列比对并修剪。研究人员计算了每条序列的多项密码子相关指标，包括有效密码子数（effective number of codons, ENc）、针对人源与禽源宿主的密码子适应指数（codon adaptation index, CAI）、GC3、相对同义密码子使用度（relative synonymous codon usage, RSCU）、密码子偏性指数（codon bias index, CPB）以及PR2。从FASTA格式文件头中提取了年份与国家元数据。本数据包包含比对后的FASTA文件、密码子指标CSV文件、质量控制（quality control, QC）报告以及分析绘图结果。本数据集由[e-mail]处理完成。
