A tool for re-annotating miRNA namelists or datasets. Obsolete annotations (either due to older miRBase versions or out-dated profiling platforms) can be converted into newer ones enforcing mature sequence correspondence. miRiadne uses the miRNA mature sequence to link miRBase versions and/or platforms to prevent nomenclature ambiguities. miRiadne was designed to simplify and support biologists and bioinformaticians in re-annotating their own miRNA lists and/or data sets.
