WebNN. Between a read mapping to both unique genomic and repeat family, if unique mapping to genome is more than 2 mismatches per read = 2 * 2 * 6 alignment score better than to repeat element, throw out repeat element and use genome mapping. Otherwise keep the repeat element mapped read. WebOct 18, 2024 · A mapper takes as input a reference genome and a set of reads. Its aim is to align each read in the set of reads on the reference genome, allowing mismatches, indels and clipping of some short fragments on the two ends of the reads: Figure 1: Illustration of the mapping process. The input consists of a set of reads and a reference genome.
