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. WebThis tool uses Bowtie2software to align single-end reads You can supply the reads in one or more files. either FASTA or FASTQ format, but all reads files need to be in the same format.

WebAs such, the FASTQ files contain reads of DNA from both mice and human cells. I expect ~30% of reads are contaminated by mice cells.
