DSSR (Dissecting the Spatial Structure of RNA) is a versatile computational tool for the analysis, annotation, modeling, and schematic of RNA/DNA structures, including G-quadruplexes ( It is built on the widely used 3DNA (3D Nucleic Acids) suite of programs but goes far beyond it in terms of capabilities, usability, and documentation. All DSSR functionalities are integrated into a single executable application (x3dna-dssr) that is just 2MB in size, has no runtime dependencies on third-party libraries, and can be readily incorporated into other bioinformatics resources and research pipelines. DSSR excels in structural bioinformatics of nucleic acids, including RNA, DNA, and their protein complexes. In this webinar, I’ll give an overview of the main features of DSSR.
