Webb3.1 Read Alignment. Align reads with STAR. STAR is one of the most common tools used for bulk RNA-seq data alignment to generate transcriptome BAM or genomic BAM output. The STAR code can be downloaded at here. A tutorial for STAR is available here. When using STAR, the first step is to create a genome index.

WebbAfter this, the number (59898883) and proportion (79.41%) of uniquely mapped reads is reported, as is the average mapped length (192.61), which indicates that on average 192.61/200 bases of our read pairs were mapped to the genome. Ideally, you want this ratio to be 75% or greater. WebbReads that map to more than 10 loci are counted as mapping to too many loci. You can change --outFilterMultimapNmax to increase the threshold.
