[Chimera-users] Creating Average Structure from PSF/DCD --> Include metal ions in final structure

Hi, I am trying to create an average structure in chimera 1.7 using the built in MDtools (loading a PSF/DCD file to get the trajectory). I am able to create an averaged structure for a select number of frames easily, but it doesn't appear that the metal ions are included when the averaging occurs. Is there someway to force the ions to be included? or alternatively, is there a script to create an average structure that includes selected atoms?
