  • 19.04.2021: Release of version 2.0.0. Our web server has been published in the NAR Webserver Issue 2021.
  • 25.10.2020: Release of version 2.0.0-rc. We added support for 7 other organisms, custom and UMI-based sequencing protocols, circular RNAs and several new analysis modules.

miRMaster 2 is a comprehensive analysis framework for sncRNA-seq data. Samples are directly preprocessed in the browser before being uploaded to our server.

Our tool quantifies miRNAs and other ncRNAs, as well as isomiRs and variants in miRNAs and predicts miRNA candidates.

Further it performs mapping against the NCBI RefSeq collection of bacterial and viral genomes, thereby allowing the detection of contaminations, infections or exogenous miRNAs.

We also provide correlation analyses, clustering and embedding analyses, as well as batch effect quantification and differential expression evaluation.
