Popgen Stats from Hufford et al. 2012 Nat. Gen.

Summary statistics for 10kb windows genome-wide and for genes in the maize v2 filtered gene set. Data are from Hufford et al. 2012: http://www.nature.com/ng/journal/v44/n7/full/ng.2309.html See details in the paper for criteria for calling SNPs, data used for statistics, etc. Columns are: locus: GRM name of gene in the filtered gene set S: number of Segregating sites ThetaW: Watterson's estimate of theta (per locus) ThetaPi: nucleotide diversity (per locus) ThetaH: Fay and Wu (2000) estimator (per locus) TajD: Tajima's D seqbp: # of bp sequenced. this should be used as the denominator to calculate per bp. values of the above statistics.本数据集包含玉米v2过滤基因集内全基因组范围的10kb窗口区域及基因区域的汇总统计数据。数据来源于Hufford等（2012）的研究成果：http://www.nature.com/ng/journal/v44/n7/full/ng.2309.html。有关单核苷酸多态性（SNP, Single Nucleotide Polymorphism）的调用标准、统计分析所用数据集等详细信息，请参见该论文。 各列含义如下： locus：过滤基因集中基因的GRM名称 S：分离位点（Segregating sites）数量 ThetaW：沃特斯θ估计值（Watterson's estimate of theta，单基因座水平） ThetaPi：核苷酸多样性（nucleotide diversity，单基因座水平） ThetaH：Fay与Wu（2000）估计量（Fay and Wu (2000) estimator，单基因座水平） TajD：田岛D统计量（Tajima's D） seqbp：测序碱基对总数量，该值可作为分母用于计算上述各统计量的每碱基对数值。
