license missing in x3dna-v2.4 file (window version)

[Jianhui Wang]

Dear Xiaogjun,

I got a problem that I could not find the license file from the x3dna-v2.4 extract files. I'm wondering if I did something wrong in this very early step for software installation?

Hi Jianhui,

Thanks for your enquiry about 'missing' the 3DNA-v2.4 license file. There is a long and complicated history regarding the 3DNA software and its licensing. Basically, the 3DNA-v2.4 software package is free for academic use, even though no license file is explicitly distributed with the  tarball.

DSSR 2.0, which has completely replaced 3DNA v2.x, has been formally licensed by Columbia University. See the overview PDF: http://docs.x3dna.org/dssr2-overview.pdf.

3DNA 2.x is no longer supported for 'free' as it used to be for the past decade. A paid DSSR license from Columbia is required for future technical support.

Best regards,

Xiang-Jun
