Platon's Squeeze

"SQUEEZE: An effective cure for the disordered solvent syndrome in crystal structure refinement."

Squeeze (along with Addsym to find missing symmetry) is generally considered one of the two killer applications within Platon. For the pros, cons and caveates of Platon's Squeeze facility, refer to the main Platon Squeeze page at:


In the WinGX menu, run Analyse, Platon, Squeeze

Running the Platon Squeeze menu option within WinGX


Platon will then do its stuff. Read the information Platon provides and press ENTER when appropriate.

When doing a cycles of refinement using Shelx (Refine, Shelx-97), you will be prompted for a dataset to choose from - now including the newly created Squeezed HKL file. Choose this and the refinement will use this "squeezed" HKL data file to refine on.

WARNING!: On the present October 2000 version of WinGX, if you spawn Shelxl-97 within SXGRAPH , it refines on the default HKL fle. Thus just use the above Refine, Shelx-97 menu if you want to be able to select which HKL file you wish to refine on.

Prompted to select HKL file type - i) none and ii) Squeezed
