title: Similarity of RNA secondary structures.
abstract: In this article, we propose a relatively similar measure to compare RNA secondary structures. We first transform an RNA secondary structure into a special sequence representation. Then, on the basis of symbolic sequence complexity, we obtain the relative distance of RNA secondary structures. The examination of similarities/dissimilarities of a set of RNA secondary structures at the 3'-terminus of different viruses illustrates the utility of the approach.
