To do this, we use the -F option (note the capitalization to denote "opposite"). samtools view -F 0x2 sample.sorted.bam WebSince paired-end sequencing is commonly used in ATAC-seq, so, we will tell MACS2 that the data is paired using the -f argument. By this way, MACS2 would only analyze properly mapped reads (as we get the bam after …
