Once in a while I receive emails from prospective users, both commercial and academic, about DSSR licensing from the Columbia Technology Venture (CTV) (http://innovation.columbia.edu/technologies/CU20391). Louis made the following explicit suggestion in a recent thread titled "Bug or feature (?) : residue numbering not understood (http://forum.x3dna.org/rna-structures/bug-or-feature-()-residue-numbering-not-understood/)":
I suggest you summarize the content of the [CTV] page in a forum post, to provide a reliable source of information about DSSR licensing, maybe?
There are two types of DSSR Pro licenses, as shown below:
- Commercial users may inquire about pricing and licensing terms by emailing techtransfer@columbia.edu (and CC to xiangjun@x3dna.org).
Academic users can obtain DSSR Pro for a one-time fee of $1000, which includes a comprehensive user manual and one year of developer support as set forth in the license agreement. Please contact techtransfer@columbia.edu (and CC to xiangjun@x3dna.org). DSSR Pro has completely superseded 3DNA, and is being continuously improved.
Users of DSSR Pro, both commercial and academic, receive first-rate support directly from the developer. The open 3DNA Forum, private email, and virtual meetings are all options for contact, depending on what is most convenient for the users.
The free DSSR Basic academic license is no longer available as of November 11, 2021. Due to a lack of government funding, only DSSR Pro is offered for academic and commercial usage as outlined above. For further information, please visit the CTV DSSR website (http://innovation.columbia.edu/technologies/CU20391).

Hi Dr. Lu!
About two years ago I downloaded DSSR version 2.0 for academic use and since then I built some work using the tool. Only now have I found out that the newest DSSR versions are not freely available anymore. And now I have a question - is it safe to freely use the old DSSR version for academic use according to the old license?
Thank you!
Best regards,
Eugene Baulin

Hi Dr. Baulin,
is it safe to freely use the old DSSR version for academic use according to the old license?
Yes. Keep in mind that such outdated versions are no longer supported or maintained.
Best regards,
