As anyone at the IUCr Glasgow Congress would have noted,
the GUI Win CRYSTALS single crystal refinement suite is now
available via the web.

Crystals has a large diversity of "integrated" facilities for structure 
analysis.  The full dictionary of instructions, directives, parameters and 
keywords is over 2,000 items.

-------

Crystals can be used for refinement of simple to highly complex single 
crystal structures.  Via the GUI, the following can be easily and 
intuitively performed:
(refer: http://www.ccp14.ac.uk/tutorial/crystals/images/guiexample01.gif)

  Guided GUI refinement manager for routine refinements
  Graphical automatic hydrogen addition
  Slant Plane Fourier Maps
  Renaming/deleting atoms
  Distance, angle, planar constraints.
  Validation Checks
  Resequencing and collecting atoms.
  Importing of structures and HKL data solved in Shelx format.
  
-------

It should be noted that while the common functions of Crystals 
work via a GUI, the scripting based tools are still maintained and
easily accessible in the software.
