##### 2 数据比对

比对结果统计如下表：

表2 比对结果统计

Type | Values
--- | ---
Reads Mapped to Genome | 96.01%
Reads Mapped Confidently to Genome | 80.77%
Reads Mapped Confidently to Intergenic Regions | 1.69%
Reads Mapped Confidently to Intronic Regions | 15.62%
Reads Mapped Confidently to Exonic Regions | 63.44%
Reads Mapped Confidently to Transcriptome | 71.64%

注：
Reads Mapped to Genomes：比对到参考基因组上的Reads在总Reads中占的比例；
Reads Mapped Confidently to Genome：比对到参考基因组并得到转录本GTF信息支持的Reads在总Reads中占的比例；
Reads Mapped Confidently to Intergenic Regions：比对到基因间区域的Reads在总Reads中占的比例；
Reads Mapped Confidently to Intronic Regions：比对到内含子区域的Reads在总Reads中占的比例；
Reads Mapped Confidently to Exonic Regions：比对到外显子区域的Reads在总Reads中占的比例；
Reads Mapped Confidently to Transcriptome：比对到已知参考转录本的Reads在总Reads中占的比例。
