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, 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 provideprivate 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. By asking your questions on the public 3DNA Forum, you are not only benefiting yourself but also the user community. I monitor the Forum regularly and respond to posts promptly -- browsing the forum should c onvince you of my dedication to 3DNA.
Here is a list of the current and previously released versions of 3DNA and related programs (DSSR, SNAP, SCHNAaP/SCHNArP).DSSR v1.6.8-2017mar28
-- DSSR is an integrated software tool for dissecting the spatial structure of RNA. The program has been designed from the ground up to make RNA structure analyses straightforward: it is self-contained and self-explanatory, thus easy to install and simple to use. Give DSSR a try, you may well end up liking it! See my blog post titled "DSSR, what's it and why bother
" for more info. Check Web-DSSR
to give it a try. [Log in and click here

paper.3DNA release v1.5 (obsolete)
(with C source code) -- no longer supported.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.
