Grade Web Server conditions of use

Global Phasing ("Developer") is pleased to offer this Web server to the crystallographic community to facilitate the generation of stereochemical restraint dictionaries for general ligands by means of its program "grade", involving among other things a call to the "Mogul" program through special arrangement with the Cambridge Crystallographic Data Centre (CCDC), whom we hereby expressly acknowledge.

Invocation of this Grade Web Server by "User" is subject to the following conditions:

• User agrees that Developer may use the ligands uploaded to this server for the purpose of debugging and further developing grade and the server.
• In return, Developer undertakes not to deliberately make public the nature of these ligands without prior permission from User, but reminds User that the security provisions on this server will not guarantee any degree of confidentiality.
• User understands that Developer may contact User by e-mail with queries about the performance of the server to help resolve problems and issues that may arise.
• Prior approval must be sought for the use of this Grade Web Server by non-interactive scripts or 3rd party applications. We encourage such use but need to make sure that it does not conflict with interactive use.
