No more grant funding for 3DNA/DSSR
« on: October 30, 2021, 09:58:15 pm »
Due to a lack of governmental funding support, we are no longer able to provide DSSR free of charge to the community. Instead, we offer DSSR Pro for academic purposes for a one-time fee of $1000, which includes one year of developer support as set forth in the license agreement, and can be requested from, copy Commercial users may inquire about pricing and licensing terms by emailing, copy DSSR Pro excels in structural bioinformatics of RNA, DNA, and their protein complexes. The software has completely superseded 3DNA, and is being continuously improved. Revenue from licensing supports the development and availability of DSSR.

My focus will now shift to DSSR Pro, and I'm committed to making it a brand that stands for quality and value. By virtue of its unmatched functionality, usability, and support, DSSR Pro would save users a substantial amount of time and effort when compared to competing options.

I designed, implemented, documented, and have continuously improved and supported DSSR. As a result, DSSR Pro users may expect a rapid and concrete answer to their questions. My track record throughout the years has unambiguously demonstrated my dedication to DSSR. I strive to ensure that paying users' trust in DSSR Pro is well-founded by providing them with the best services possible.

As a general rule, the CTV does not provide an evaluation license of DSSR Pro. Potential users should watch the DSSR overview video (20m), browse the Forum, and read DSSR-related papers. If they still have questions or want to see a live demo, I would be pleased to accommodate them. Although more DSSR Pro licenses are definitely beneficial, I do not have the time or desire to directly promote the product, including sending bulk emails to Forum registered users. As the developer, I can only strive to make DSSR Pro the best it can be and let the rest sort itself out. I am a strong believer of the old Chinese saying: "酒香不怕巷子深" (Good wine needs no bush).

3DNA and DSSR Basic are obsolete and will no longer be maintained or supported. The following three web resources, however, are freely available to the public and require no registration:
I aim to keep the 3DNA Forum up and running so that users can help one another and the material remains available. I may chime in occasionally, but I won't be able to continue serving the community for free as I have over the past decade.
