Hi,
here is a new MAIN release, the major novelity is a user oriented manual(s) organization (Users' guide)... Besides there are a few minor new things as an UN_DO option and improved CONNECT in model building, a new approach to partial model refinement with MIR restraints etc... For US community users the '_US.ps' manual files have been created. These will hopefully, when printed, include entire manual pages.
Do not FTP unnecessary files:
NCS positional constraints became part of MAIN now. See in Refinement
... Also hard restraints allow matrix changes.
