Reads duplication
WebJul 13, 2024 · While the notion that more PCR amplification increases artefactual duplicate reads in high-throughput sequencing makes intuitive sense and is widely accepted, high PCR cycle numbers are often necessitated by scarce starting materials, another likely cause for duplicate reads. Thus, the contribution of PCR cycle number to PCR duplicates is often ... 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. …

WebJan 2, 2014 · An alternative source of read duplication is sampling coincidence, whereby inserts are fragmented at identical genomic positions during library construction. The practice of removing duplicate reads is well justified only when the sequencing depth is low and sampling coincidence is unlikely. WebApr 15, 2016 · Researchers at the Institute of Molecular Biology, Mainz, Germany have devloped the tool dupRadar, which provides an easy means to distinguish artefactual from natural duplicate reads in RNA-Seq data. dupRadar assesses the fraction of duplicate reads per gene dependent on the expression level.
