We propose a 4-D representation of RNA secondary structures. The four-dimensional representation resolves structures’ degeneracy and avoids loss of information and the limitation that different structures correspond the same plot set (or presentation). The RNA pseudoknpts also can be represented as four-dimensional representations. Based on this representation, we outline an approach to compute the similarities between six RNA secondary structures for illustrating the utility of our approach.
