What is the legal status of XPLOR-NIH with respect to code previously contributed to CNS? I am wondering if it is possible for any of the original CNS contributors to take code they wrote for CNS outside of Brunger's lab, and contribute it to XPLOR-NIH?
Also, how much freedom/responsiblity do users have in code modifications? The lincense in the source dir states to report modifications to Yale. The download license seems to request modifications to be sent to NIH. Do authors of modifications retain rights to those modifications, and can we redistribute them? For the short term, I would like to utilize parts of XPLOR-NIH as a crystallographic force-field engine, as a sort of library. Long term plans would probably be to contribute code to XPLOR-NIH, but it would be nice to know that contributions are legally protected long term from for-profit groups, to avoid the CNS/CNX scenario. How much interest do the XPLOR-NIH developers have in implementing high-quality force fileds, like MMFF for ligands, good attempts at eletrostatics, etc? It seems there is some interest, since you've added Generalized Borne. THANKS, Joe Krahn
