1.supplementary alignment supplementary alignment是指一条read的一部分和参考区域1比对成功,另一部分和参考区域2比对成功,参考区域1和参考区域2没有交集(或很少),那么一条read就会产生两条sam文件, 将其中的一条sam文件作为represent alignment,而另一条作为supplementary alignment (flag为2048). 将上面的fastq文件去跑bwa,read有两条sam文件,第二条的flag值为2048:…

现在BWA大家基本上只用其mem算法了,无论是二代还是三代比对到参考基因组上,BWA应用得最多的就是在重测序方面. Aligning sequence reads, clone sequences and assembly contigs with BWA-MEM - arXiv:1303.3997v2 摘要 BWA-MEM is a new alignment algorithm for aligning sequence reads or assembly contigs against a…

Reference Genome Components 1. GRCh38 is special because it has alternate contigs that represent population haplotypes. Don't know alternate contig from alternate dimension? Spend five minutes now to review terminology in our Dictionary entryReferenc…

一.bwa比对软件的使用 1.对参考基因组构建索引 bwa index -a bwtsw hg19.fa   #  -a 参数:is[默认] or bwtsw,即bwa构建索引的两种算法,两种算法都是基于BWT的(BWT search while the CIGAR string by Smith-Waterman alignment.).-a bwtsw对于短的参考序列是不工作的,必须要大于等于10Mb:-a is 不适用于大的参考序列,必须要小于等于2G: output:hg19.fa.am…
