WebFilter to keep only uniquely mapping reads (this will also remove any unmapped reads) 1. Changing file format from SAM to BAM. While the SAM alignment file output by Bowtie2 is human readable, we need a BAM alignment file for downstream tools. Therefore, we will use Samtools to convert the file formats. WebApr 14, 2024 · High quality paired alignments (mapping quality ≥ 30) were extracted with samtools v1.9 after filtering unmapped reads, mate unmapped reads, not primary alignments, reads failing platform.

WebJun 7, 2024 · The concept of "uniquely mapped reads" is a loaded term, and most sources suggest filtering by MAPQ should do the trick. However, this approach doesn't seem to work when using BWA as a read mapper. Uniquely mapped reads (i.e. a read that maps to a single location in the genome) are sometimes preferred when running analyses that depend on … WebDec 5, 2016 · Now I’m using samtools to analyze the result. I want to extract the reads that map to more than one place in the genome, and this is my command line: Samtools view –h –f 0x100 in.bam > out.sam There are no output alignmens in the out.sam except the head, which means there are no multi-mapped reads
