Thank you, it works well. ---Original--- From: "Elaine Meng"<meng@cgl.ucsf.edu> Date: Tue, May 12, 2020 22:46 PM To: "李雄俊"<lixiongjun228@qq.com>; Cc: "chimera-users"<chimera-users@cgl.ucsf.edu>; Subject: Re: [Chimera-users] How to save a dragged pdb See the "Save relative to" near the bottom of the PDB Save dialog. In your image it is saving relative to #0, a pdb file. You need to change the model in that line to the map model. You can check in the Model Panel (menu: Favorites... Model Panel) to see which models are which numbers. I hope this helps, Elaine ----- Elaine C.
