REFINEMENT |
REFINEMENT
Refinement with REFMAC5 requires reflection data, a set of model coordinates, and
a library defining the restraints for standard groups. If a non-standard group is
encountered (in the REVIEW mode), the user has to build up a set of restraints through
the use of SKETCHER/LIBCHECK.

The plain rectangular boxes represent
tasks as in the
CCP4 Graphical User Interface, the steps to take for refinement.
The ellipsoids represent the input and output to and from the various tasks.
