Reads duplication

WebJul 25, 2016 · PCR duplicates are sequence reads that result from sequencing two or more copies of the exact same DNA fragment, which, at worst, may contain erroneous mutations introduced during PCR amplification, or, at the very least, make the occurrence of the allele (s) sequenced in duplicates appear proportionately more often than it should compared to … WebMarkDuplicates (Picard): Identifies duplicate reads. This tool locates and tags duplicate reads in a BAM or SAM file, where duplicate reads are defined as originating from a single fragment of DNA. Duplicates can arise during sample preparation e.g. …
