Provides a comprehensive perspective and understanding of RNA motif three-dimensional structure, function, tertiary interactions and their relationships. The web interface provides a straightforward but flexible means to explore the multi‐layered classification of SCOR. Users are given a standard set of icons and buttons to navigate the classes. The interface allows the user to view multiple parallel classes, subclasses (i.e. child classes) and paths simultaneously. The user may also choose to focus on a single class or path along a branch of the hierarchy—or may choose a combination of views.
