NorahDesk

A small non-coding RNA (ncRNA) detection tool for RNA sequencing (RNA-Seq) data. NorahDesk utilizes the coverage-distribution of small RNA sequence data and thermodynamic assessments of secondary structure to reliably predict and annotate ncRNA classes. NorahDesk is particularly suitable for the prediction of piRNAs as it is the first program to "annotate by association": if novel transcripts form a thermodynamically stable secondary structure with already known piRNA transcripts, it is likely that the unannotated contigs are also piRNAs.
