Dear Wandu, It might be smeared density because it is missing from your phasing model, so no reason to reinvent the wheel with MD and Phaser. You see electron density features for the domain and you know its basic structure. You can place the domain manually - it would take you five minutes and then you can proceed to refine the position by rigid body refinement and ordinary refinement/rebuilding
