For those junction reads that cannot be directly mapped, they will be sliced into multiple seeds with length k to retry the mapping, which resembles the BLAST method ... WebMapping is only the first step of RNA-Seq data analysis. We still need to assemble these reads into transcripts, and estimate their expression levels. After correctly mapping …

WebFor RNA-seq, we need to align or map each read back to the genome, to see which gene produced it. Highly expressed genes will generate lots of transcripts, so there will be lots of reads that map back to the position of that transcript in the genome. The per-gene data we work with in an RNA-seq experiment are counts: the number of reads from ...
