DSSR has completely superseded 3DNA with more advanced features and greatly improved usability.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. From version 2.0 (released around the summer of 2020), DSSR has been licensed by the
Columbia Technology Ventures (CTV), who manages the free DSSR Academic licenses as well as paid DSSR Pro licenses for both academic and commercial users. I've lately learned academic users from certain countries having trouble in getting DSSR Academic licenses. This pre-licensed version is provided (
as is) here to fill the gap: it is slightly outdated but still works well. Whenever possible, however, users should obtain the latest version of
DSSR through CTV --- it is free for academic uses and fully supported by the NIH R24GM153869 grant.
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.
