CONTOUR SQUEEZE MAP

Contouring of a SQUEEZE Fourier map. This option features a special difference Fourier map where F(obs) is assigned a phase corresponding to F(calc) based on both the contributions of the ordered part of the model and the disordered part (as obtained by back-Fourier transformation of the density found in the disorder region) of the structure. F(calc) consists of the contribution of the ordered part of the structure.

A SQUEEZE map should provide a clearer image of the density in a disorder region than obtainable with a standard difference map where Fobs is assigned the phase of Fcalc.

A prior SQUEEZE calculation, providing the relevant information on '.hkp' is required for this option.
