[Chimera-users] Question about electron density map

Dear Developer, I want to have a figure of my ligand only and its electron density, and I used my protein mtz file to generate a CCD4 map in phenix and then open in chimera. I tried fit in map but it does not fit well. Could you please help me out? And after I have the electron density, how to hide the backbone electron density? Thanks a lot! Best, Bixia
