Hello everybody, I am generating figures showing the electron density map around the ligands. I deleted the ligands from final co-ordinate file and then performed refinement with identical parameters as before while keeping simulated annealing=true. I shall be thankful if someone could suggest me whether I consider mFo-DFc map or 2mFo-DFc map or both. Kindly also tell me the minimum acceptable contour level required for showing difference map. All structures are at 1.4 - 2.0 angstrom resolutions. Regards, Bishal
