WebAug 29, 2024 · BWA-MEM, Bowtie2 and Minimap2 were not designed to map against redundant databases, as they are based on unique mappings and therefore do not deal with multi mapping reads. This is also reflected by MGmapper, albeit relying on only one unique mapping. Salmon was designed to predict RNA transcript levels, which includes a … WebSo to actually quantify the genes, we will map the input reads back to the assembly. There are many different mappers available to map your reads back to the assemblies. Usually they result in a SAM or BAM file . Those are formats that contain the alignment information, where BAM is the binary version of the plain text SAM format.
