Multi-fasta file of variable SNP positions in 2000+ Staphylococcus aureus genomes

N315 is the reference strain. Each genome downloaded from NCBI SRA and aligned using BWA. SNPs called using GCAT.N315为参考菌株（reference strain）。从NCBI序列读取档案（Sequence Read Archive, SRA）下载的各基因组均采用BWA（Burrows-Wheeler Aligner）完成序列比对。单核苷酸多态性（Single Nucleotide Polymorphism, SNPs）通过GCAT工具完成调用。
