 [STAR](https://github.com/alexdobin/STAR) is a read aligner designed for splice aware mapping typical of RNA sequencing data. STAR stands for *S*pliced *T*ranscripts *A*lignment to a *R*eference, and has been shown to have high accuracy and outperforms other aligners by more than a factor of 50 in mapping speed, but it is memory intensive. Using `--aligner star_salmon` is the default alignment and quantification option.
 
 The STAR section of the MultiQC report shows a bar plot with alignment rates: good samples should have most reads as _Uniquely mapped_ and few _Unmapped_ reads.
