Hi,
what is the difference simulated annealing map and how can i generate it > - difference map is a Fourier synthesis i*Fo-j*Fc, where i and j are some weights, and Fo and Fc are observed and calculated amplitudes of structure factors; - "difference simulated annealing map" is the above map calculated after a SA run; - "how can i generate it": a possible option: phenix.refine (and phenix.maps) will do it: http://www.phenix-online.org Hope this helps, Pavel.
