[phenixbb] anomalous difference map

Hi, phenix users, A difference map is used to identify whether there is anything not-modeled, say some ligands, ions. Then when I generate anomalous difference map, I should not put the ligand(which contains Br) in the model, right? Or in phenix, after I put the Br-ligand in the model, I should not see the anomalous difference density at the site, right? Could anyone give me a confirmation of this? Thanks!
