jViz.RNA 4.0

jViz.Rna 4.0 is the newest extension of jViz.RNA. A multi-platform visualization tool inspired by feedback from life sciences experts, jViz.RNA 4.0 provides faster and better RNA visualizations for all RNA classes. RNA structures can be explored, manipulated, and edited to fit the needs of any user. Any of the produced visualizations can be saved as an image format to enable easy usage in publications and presentations.


  • Multi-platform capability

    jViz.RNA 4.0 is built using Java 1.6, enabling usage on Linux, Mac OS X, and Windows.

  • Pseudoknot Visualization

    jViz.RNA 4.0 is capable of visualization of all biologically available pseudoknots.

  • Faster Dynamic Visualization

    Using state-of-the-art integration systems, jViz.RNA provides a dynamic structure which quickly responds to user manipulation. This software will provide an automatic layout which users can then edit to fit their needs.

  • Online Editing

    Structures can be edited by removing or adding base-pairs into the structure, allowing users to create related RNA structures with ease, or create an entirely new RNA structure using only the RNA sequence

  • Structure Management

    Load as many structures as you'd like and jViz.RNA will allow you to switch between them quickly as you explore their similarities and differences.

jViz.RNA 2.0

jViz.Rna 2.0 is a multi-platform visualization tool capable of displaying and comparing RNA secondary structures encoded in a number of file formats. Structures can be shown using six different visualization modes including a numerical analysis mode which includes sensitivity and specificity. Any of the drawings and data produced can be saved in a variety of formats enabling easy usage in publications and presentations.


Multi-platform capability

jViz.Rna is built using Java 1.5, enabling usage on Linux, Mac OS X, and Windows.

Flexibility with files

Not only can RNA Structures be loaded from a variety of file types, they can also be converted and saved in any of the supported formats as well. Supported structure file formats are: ConnecT (.ct), Base Pair Sequence (.bpseq), and Dot Bracket Notation (.dbf, .dbn). The resulting visualizations can be saved in the Encapsulated Postscript (.eps) format for high quality vector graphics or the PNG format for other uses.

Structure Management

Load as many structures as you'd like and jViz.Rna will group them by their nucleotide sequence. Show and hide structures by clicking on their checkbox or change their color by clicking on the small color swatch by their filename.

A Choice of Visualizations

Depending on the size and complexity of the structure, you can choose to use the Linear Feynman, Circular Feynman, Dot Plot, Classical Structure, or the Dual Graph visualization mode to display the structure. With the exception of the Dual Graph, which is limited to H-type Pseudoknots, the other visualization modes can display all possible pseudoknot types.

Configurable and Dynamic

Each of the visualization modes has its own set of configurable options. From changing the size of the text to the thickness of the lines, each view can be tweaked to best display your structure. In the Classical Structure mode, the spring model allows you to grab any nucleotide and drag it where you'd like.

Comparison of Structures

All visualization modes are capable of displaying at least two structures with the same sequence overlapped upon each other. Set one of the structures to the native fold of an organism and the other to a prediction to instantly see the accuracy of the prediction. As well, any number of structures can be compared in the Statistics view where the data is summarized in graphs or can be exported to a spreadsheet.
