Hi, First, I wanna thank you for all your work to develop ChimeraX, it’s so powerful. I do have a question and would like to have your input. I opened a EM density map (.mrc) and two pdb files in chimerax (version 1.2), then fit all the pdb models into the EM map. Then, I hide the EM map, only show the pdb models after fitting, and then I would like to save these all pdb files in a new pdb file with all position information after fitting. Would you please give me any direction how to do this? I tried saving them, but only partial pdb files saved, also tried combine commend, but it said no such commend. Thank you very much!
