‒ an integrated web server for identifying functional RNA motifs and sites
Home Scan Statistics Documentation Tutorial Release 2.0, Jun. 2012

  System Architecture

We developed an integrated web server, namely RegRNA 2.0, to comprehensively identify homologs of functional RNA motifs and sites in an RNA sequence. Various analytical approaches and data sources were incorporated into RegRNA 2.0. Through our easy-to-use web server, user can conveniently use these programs without having to download the code and get the programs to run. The predictive results and related information are presented with good graphical visualization on RegRNA 2.0 web page. The research components of RegRNA 2.0 are shown as figure below :


As compared with RegRNA, RegRNA 2.0 integrates more data and is capable of identifying more types of functional RNA motifs (as shown in Table below). In addition, RegRNA 2.0 provides further analysis and related information for predictive results, and presents results with good graphical visualization.
