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. WebSep 30, 2024 · For those reads that can map to both and align better to the ALT contig, the tool flags the ALT contig alignment record as supplementary (0x800). This is what we call alt-aware mapping or alt-handling. Adding the -j option to the command disables the alt-handling. Reads that can map multiply are given low or zero MAPQ scores. green flash hours
