Comparison of graphical software for RNA secondary structure analysis

List of related software

We compare related graphically oriented software for RNA secondary structure comparison including the following applications:

1. R-chie: Produces various similar forms of arc diagrams for secondary structures (package and graphical library based on the R language)
2. VARNA: Java-applet-based viewer of radial layout diagrams for secondary structures
3. RNAbows: Web interface combining multiple RNA software packages
4. Forna: RNA secondary structure visualization using a force directed graph layout (hosted by the ViennaRNA site)
5. jViz.rna: Supports a GUI based view of radial diagrams for structures and pseudo knot visualization ✔️

Feature-by-feature comparison chart notation

The following tables compare the features of other software applications with visualization features similar to that of RNAStructViz. In the table, the columns denote inclusion of the features listed to the left as rows. We use ✔️ to denote that a particular application implements a key feature specification, ❌ to denote that an application does not implement a key listed feature, and 〰️ to denote a partial implementation. We also use 💥 or 〰️ to denote partial OS platform support, e.g., Windows support should work, but is not confirmed by our tests. Where possible, we attempt to annotate the wide bins we use to classify the features of these applications with footnotes given below the table. This table was last compiled in August of 2020 with the current feature set implemented by each program.
