How to deduplicate PCR Nature Methods

WebFor every group of duplicate reads, a single representative read is retained.The following criteria are applied to select the read that will be retained from a group of duplicated reads: 1. The read with the lowest number of mapping coordinates (see --multimapping-detection-method option) 2. The read with the highest mapping quality. WebDuplicate reads can also result from a single amplification cluster, incorrectly detected as multiple clusters by the optical sensor of the sequencing instrument. These duplication … WebJan 26, 2024 · All of these samflag 0x400 reads have an xf tag value of 17, which consist of bits 1 and 16. This also means these reads do not have the xf bit of 8, which mark representative reads from a group of duplicates. The converse isn't true though. The xf17 consist mostly of samflag 0x400 duplicate reads but also of samflag nonduplicate reads. highveld honey benoni
