Additional file 4: Dataset S1. of No evidence for a bovine mastitis Escherichia coli pathotype

This zip archive contains the binary presence/absence matrix of 13,481 OGs in the 25 bovine-associated E. coli genomes and the R script for the Fisherâ s exact tests to test the associations of OGs/VFs with either pathotype or phylogroup (A/B1). The R script includes also code to create the Manhattan plots in Additional file 3: Figure S3. The binary presence/absence matrix of virulence-associated genes needed as second input for the R script is enclosed in Additional file 14: Dataset S7. (ZIP 16 kb)

本压缩包包含25株牛源大肠杆菌基因组中13481个直系同源基因簇（Orthologous Groups，OGs）的二元存在/缺失矩阵，以及用于检验OGs/毒力因子（Virulence Factors，VFs）与致病型或系统发育群（A/B1）关联性的费希尔精确检验（Fisher’s exact tests）R脚本。该R脚本还附带了用于生成附加文件3中图S3的曼哈顿图（Manhattan plots）的代码。供该R脚本使用的第二个输入文件，即毒力相关基因的二元存在/缺失矩阵，已收录于附加文件14：数据集S7。（压缩包大小：16 kb）
