Enhanced Read Analysis of Gene Expression ERANGE

A software tool for mapping and quantifying Mammalian transcriptomes by RNA-Seq. The functions of ERANGE are to (i) assign reads that map uniquely in the genome to their site of origin and, for reads that match equally well to several sites ('multireads'), assign them to their most likely site(s) of origin; (ii) detect splice-crossing reads and assign them to their gene of origin; (iii) organize reads that cluster together, but do not map to an already known exon, into candidate exons or parts of exons; and (iv) calculate the prevalence of transcripts from each known or newly proposed RNA, based on normalized counts of unique reads, spliced reads and multireads.
