RNA structures (DSSR) / Re: Where to download the DSSR basic version

Dear Xiang-Jun,

I am sorry that I failed to catch up the information. Now it is clear enough for people like me to find the DSSR download information. I very appreciate it and thanks a lot.

Best regards,

Hi Ying,

DSSR may only be downloaded from the Columbia Technology Venture (CTV) website. I've included a link to the CTV website in several places on this 3DNA Forum. I'm surprised that users like you are still having trouble locating where to get DSSR.

To clarify, I changed the header link "DSSR License" to "DSSR Download/Licensing". The DSSR download link is also included in my signature at the bottom of each of my posts. See also the post "Clarification on DSSR licensing".

Registration on the 3DNA Forum is required in order to obtain the classic 3DNA v2.4 (and SCHNAaP/SCHNArP), and ask 3DNA/DSSR-related questions.

Please let me know if there is anything else I can do to make this message crystal clear.

Best regards,

Dear Sir,
I followed the instructions to register, got the confirmation link and logged in apparently properly, I did a lot research but still could not find the link to download the DSSR basic for academic study. Is the program still available?

As a followup, DSSR Pro now has the option to derive only pairs across chains.
Thank you for your reply.

Best wishes
DSSR Basic does not have the base mutations feature at all. Also note that DSSR Basic is provided AS IS without any warranty of support.

That said, DSSR Basic does include features described in the three DSSR papers (2015 DSSR, 2017 DSSR-Jmol, and 2020 DSSR-PyMOL, all published in NAR) so that reported results can be reproduced. The DSSR Basic manual should function as expected. Anything to the contrary will be considered a bug and will be fixed as soon as possible.

DSSR Pro includes new advanced features, plus all functionality of 3DNA v2.4, as well as full support. Please watch the DSSR Overview Video.

Instead of DSSR/3DNA v2.4, you may want to try other software tools such as RNAView, FR3D, MC-Annotate, or Curves+ etc. Please let us know what you find.

Best regards,

Through another attempt, I found a solution to the problem.

Please elaborate on what you did that resulted in a solution to the problem.


Sorry to bother you again, but I would like to confirm if this feature is available in dssr-basic? Because I may not be able to afford the pro for now. I looked at the manual for basic and it doesn't seem to have this feature.
I sincerely thank you for your reply. Through another attempt, I found a solution to the problem.

I wish you a happy work and life.
