RE: OMIT-map

[Többens , Daniel]

This seems to be another name for a difference Fourier map, calculated from F_obs - F_calc; the term omit map being used in the macromolecular community. It shows scattering density missing in the model, i.e. from omitted atoms.

*Betreff:* OMIT-map

Dear All,
I received the answer from a referee for an article about an organic structure 
I determined. The referee asks for An omit map (including contour level) for 
all ligand-bound crystal structures.  I searched about omit-map, but I did not 
find a clear how to calculate this map.
Can anyone send me something about the omit-map or explain me how to obtain 
these maps with GSAG or TOPAS?

Thanks


Davide Levy
