Reads duplication

WebNov 13, 2024 · EDIT: I do not want to make any modifications to the mapped reads, I simply want to ignore one read in a read pair if they overlap the same region. I used samtools depth to calculate the depth of coverage for samples in the whole Exome region using a GRCh37_ref.bed. These samples are sorted and duplicate marked. 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. …
