STAR generates output files that can be used for many downstream analyses such as transcript/gene expression quantification, differential gene expression, novel isoform reconstruction, signal visualization, and so forth. STAR can align spliced sequences of any length with moderate error rates providing scalability for emerging sequencing technologies. In addition to detecting of annotated and novel splice junctions, STAR is capable of discovering more complex RNA sequence arrangements, such as chimeric and circular RNA. ![]() The STAR ( Dobin et al, 2013) software package enables highly accurate and ultra-fast alignment of RNA-seq reads to a reference genome. derived from the non-contiguous regions of the genome. This task presents more challenges than alignment of genomic DNA reads because RNA sequences are often spliced, i.e. One of the foundational steps in the RNA-seq data analysis is mapping (alignment) of the large sets of sequenced reads to a reference genome. ![]() Recent advances in the high-throughput sequencing have made sequencing of RNA transcripts (RNA-seq) an attractive tool for the studies of the transcriptome at single nucleotide resolution. ![]()
