Clarification on DSSR licensing
« on: May 31, 2021, 01:58:55 pm »
Once in a while I receive emails from prospective users, both commercial and academic, about DSSR licensing from the Columbia Technology Venture (CTV). Louis made the following explicit suggestion in a recent thread titled "Bug or feature (?) : residue numbering not understood":

Quote from: Louis
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?

The different DSSR license types are thus summarized below:
  • Commercial users may inquire about pricing and licensing terms by emailing techtransfer@columbia.edu.

  • Academic users can obtain the DSSR Pro license ($1000) by contacting techtransfer@columbia.edu. It is a one-time fee and does not cover future major releases of the software. Minor releases with bug-fixes and small updates are included in the fee. In reality, I do not expect another major release of DSSR in the next four years. As a result, the average annual cost is $250, which is about a tenth of the cost of a journal publication or a two-night hotel stay.

    DSSR Pro includes advanced capabilities for model building, additional features in structural analyses, annotations, and visualizations. It comes with a comprehensive user manual, as well as one year of technical support from me.

  • Academic users can also obtain the free DSSR Basic license from the CTV website. DSSR Basic includes 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. DSSR Basic is provided "as is" without any warranty of support.

My top priority is to provide the best support possible for commercial or academic users of DSSR Pro. For the benefit of the community, the open 3DNA Forum is the preferred method of communication. On the other hand, I'm fine with email or virtual meetings if that's what the DSSR Pro users want.

Free academic users of DSSR Basic are welcome to ask DSSR-related questions on the 3DNA Forum. I will fix any reported and verified bugs as soon as possible. I might also be available to answer general questions, especially about reproducing published results or document features. Requests for additional features, however, may necessitate an upgrade to DSSR Pro. I would only respond to questions from free academic users via the open 3DNA Forum; no email or virtual meetings.

Please contact CTV via email (techtransfer@columbia.edu) if you have any additional questions about DSSR licensing. If you are having trouble contacting CTV via its DSSR website or email, please report here.

PS: Chrome is the best browser for accessing the DSSR website on the CTV. Safari (on macOS) and Opera have also been reported to work flawlessly. On the other hand, you may experience issues with these browsers: Firefox, Edge, or Vivaldi.
