Summary of features considered for random forest classifier.

Each feature is considered for determining whether the alignment of the read in SAM format corresponds to mtDNA or a NUMT. The SAM Tag field indicates the corresponding field in the SAM alignment format specification. Features in bold were used in the final model for the random forest classifier.

我们将考量每一项特征，以判定SAM格式（Sequence Alignment/Map格式）中的测序读段（read）比对结果，究竟对应线粒体DNA（mtDNA，mitochondrial DNA）还是核线粒体DNA片段（NUMT，nuclear mitochondrial DNA segments）。SAM标签字段对应SAM比对格式规范中的相应字段。本次随机森林分类器的最终模型中，使用了标粗的特征项。
