DSSR has completely superseded 3DNA with more advanced features and greatly improved usability. Please visit the Columbia Technology Ventures (CTV) website for obtaining the latest version of DSSR.

To download 3DNA v2.4, users must first register in the 3DNA Forum using their work email. After verification and activation, users can then login to see the Downloads section (see the screenshot below). Click links on that page to download 3DNA and other programs (listed below). Note that command-line tools such as wget and curl are blocked on purpose.

DSSR v1.9.10-2020apr23 --- This version corresponds to the paper "DSSR-enabled innovative schematics of 3D nucleic acid structures with PyMOL" (2020) in Nucleic Acids Research.

3DNA v2.4.8-2023nov10 (with C source code, distributed under the CC-BY-NC-4.0 license; obsoleted by DSSR!) -- What's new?. Follow the instructions on "How to install 3DNA on Linux (macOS) and Windows?" and post back any questions you may have.

SCHNAaP/SCHNArP (with C source code, distributed under the CC-BY-NC-4.0 license) -- this package is a bit aged in applicability, but the algorithms implemented there are straightforward, easy to understand, and still valid.

Hello everyone, how can I get the old version of the program, or how can the new version 2.4 program run through the pymol script. (No x3dna-dssr.exe found in the new program)

Only 3DNA v2.4.8-2023nov10 is available for download. The ANSI C source code and Ruby scripts are included in the package, along with precompiled binaries for Linux and macOS. The Linux version should also work under Windows using WSL2. In any case, you can compile the source code easily as long as you have a C compiler installed on your system.
