Download instructions
« on: February 25, 2012, 12:48:38 am »
Starting from 3DNA v2.1, we have streamlined the download procedure. Users just need to register in the 3DNA Forum (which normally takes no more than a few minutes) and then login to see the Downloads section where all released and beta test versions of 3DNA and related programs can be downloaded. Moreover, with the same registration, users can post 3DNA-related questions directly in the Forum.

To re-emphasize, you must register and log in to see the Download section (see the screenshot below), and then click *links at that page* to download 3DNA and related programs; specifically, command-line tools such as wget and curl are blocked on purpose. This page is for instructional purposes only; it does not contain active download links.

I strive to continuously improve and extend 3DNA's functionalities for real-world applications. Your comments, suggestions, and bug reports are more than appreciated -- I take careful note of each user feedback. Please be aware that for the benefit of the 3DNA-user community at large, I do not provide private email/personal message support; the Forum has been created specifically for open discussions of all 3DNA-related issues. In other words, any 3DNA-associated questions are welcome and should be directed here.

Specifically, please do not be shy in sharing openly and concretely any difficult/negative experiences you may have in installing or using the software. Presumably, I've made the message simple and clear enough to get across without further explanation. See also the FAQ entry "How to make the best use of the Forum".

By asking your questions on the public 3DNA Forum, you are benefiting not only yourself but also the user community. I monitor the Forum regularly and respond to posts promptly -- browsing the Forum should convince you of my dedication to 3DNA.


DSSR 2.0 has been released, with a professional user manual. Here is an overview of DSSR 2.0. It surpasses 3DNA v2.4, with vastly expanded features and dramatically improved usability. DSSR 2.0 is licensed by Columbia University. Please visit the Columbia Technology Ventures (CTV) website to obtain a license and to download DSSR.

Here is the list of programs (SNAP, 3DNA v2.4, and SCHNAaP/SCHNArP) that can be downloaded from the 3DNA Forum:

SNAP v1.0.6-2019sep30 -- SNAP is a software program for the characterization of three-dimensional Structures of Nucleic Acid-Protein complexes, currently in beta testing release, but fully functional. It shares the same codebase as DSSR.

3DNA v2.4.4-2019sep09 (with C source code; obsoleted by DSSR!) -- What's new?. [Log in and click here to see the active download page.] 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) -- this package is a bit aged in applicability, but the algorithms implemented there are straightforward, easy to understand, and still valid.
