Additional file 2: of Analysis of codon usage patterns in Hirudinaria manillensis reveals a preference for GC-ending codons caused by dominant selection constraints

The RSCU values of each sequence and the first 2 PCA factors. This file contains all the calculated RSCU values of each sequence and the first 2 PCA factors. The stop codons were not included and thusly this file has 62 columns. The beginning of each column shows the specific meanings of the different value types. (XLSX 6743 kb)本数据集包含各序列的相对同义密码子使用偏性（Relative Synonymous Codon Usage, RSCU）值与前2个主成分分析（Principal Component Analysis, PCA）因子。本文件收录了所有序列经计算得到的上述两类数值，且未纳入终止密码子，因此该文件共包含62列数据。每列的开头标注了各数值类型的具体含义。（XLSX格式，文件大小6743 KB）
