Summary of SNV class by matrix.

For each 12 row by 12 column matrix of libraries sequenced, the number of Pinnable, Multiple and Singleton single nucleotide variants is given. Also indicated is the percentage of each variant class that is catalogued in dbSNP. The number of total variants for each of the classes represents the total unique number of variants from all four matrices.针对每个经测序的12行×12列文库矩阵，本数据集给出了可锚定（Pinnable）、多重（Multiple）及单例（Singleton）单核苷酸变异体（single nucleotide variants, SNV）的数量；同时还标注了每一类变异体在dbSNP数据库中被收录的占比。各类变异体的总计数，代表了全部四个矩阵中所得到的唯一变异体的总数量。
