A review of the available single nucleotide polymorphism (SNP) calling procedures for Illumina high-throughput sequencing (HTS) platform data reveals that most rely mainly on base-calling and mapping qualities as sources of error when calling SNPs. Thus, errors not involved in base-calling or alignment, such as those in genomic sample preparation, are not accounted for.
A novel method of consensus and SNP calling, Genotype Model Selection (GeMS), is given which accounts for the errors that occur during the preparation of the genomic sample. Simulations and real data analyses indicate that GeMS has the best performance balance of sensitivity and positive predictive value among the tested SNP callers.

对现有的用于 Illumina 高通量测序 (HTS) 平台数据的单核苷酸多态性 (SNP) 调用程序的回顾表明，大多数程序主要依赖碱基调用和映射质量作为 SNP 调用的误差源。因此，未涉及碱基调用或比对的误差，例如基因组样本制备中的误差，未被考虑在内。
给出了一种新的共识和 SNP 调用方法，基因型模型选择 (GeMS)，它考虑了基因组样本制备过程中发生的误差。模拟和真实数据分析表明，GeMS 在测试的 SNP 调用程序中具有最佳的灵敏度和阳性预测值的性能平衡。
