SNP VCF file

VCF file containing info for SNPs called using the getsnpsfrommpileup.pl script. Settings used were: coverage >= 10, freq. of minor allele >= 0.2, read support for minor allele >= 3, number of alleles = 2. All SNPs were also verified using the program SysCall, and were retained only if the posterior probability of being a variant was >= 0.95.本数据集为VCF（变异呼叫格式，Variant Call Format）文件，包含通过getsnpsfrommpileup.pl脚本调用得到的单核苷酸多态性（Single Nucleotide Polymorphisms, SNPs）信息。本次分析采用的过滤参数如下：测序深度≥10、次要等位基因频率≥0.2、次要等位基因的测序读段支持数≥3，且等位基因总数为2。所有筛选得到的SNPs均通过SysCall程序进行验证，仅保留变异位点后验概率≥0.95的结果。
