XS:i:<N>标签是在多个比对时才会出现(multi mapping reads)。 所以用grep -v "XS:i"命令即可实现将不包含XS:i标签的例子全部提取出来。 bowtie2提取唯一比对的命令总结 grep "AS:" aligned.sam | grep –v "XS:" > unique_alignments.sam HISAT2 HISAT2输出sam文件的标签: ZS:i:<N>: Alignment sco...
HISAT2 Bowtie2 提取唯一比对 unique mapping reads 在生物信息学中,比对是分析RNA-seq数据的关键步骤之一,比对是将测序数据与参考基因组进行匹配的过程,以确定每个reads在基因组上的位置,HISAT2和Bowtie2是常用的比对工具,它们可以有效地将reads与参考基因组进行比对,在本篇文章中,我们将介绍如何使用HISAT2和Bowt...
在进行正式的mapping记录之前,先记录一下bwa与bowtie2在mapping这个环节的情况。 一般对于WGS结果的mapping,一般推荐的软件有两款,分别是bwa和bowtie2,大多数的公司报告或者网上的教程,我所看到的都是使用bwa进行比对的,这里,我来进行一下两个软件的对比。 实验对象还是之前文章提到的那个样本的数据,我只取用其中的...
We say an alignment is unique if it has a much higher alignment score than all the other possible alignments. The bigger the gap between the best alignment's score and the second-best alignment's score, the more unique the best alignment, and the higher its mapping quality should be....

Well, here you see him being the center of attention on St George Street which is the unique shopping district of St. Augustine. As we walked up and down the area Henry received many comments. Most of them were very positive. Some of them could have gone either way. While we know, ...
