4991	CA-only PDB shown as stick-dots	Elaine Meng	Eric Pettersen	I couldn't think of a CA-only structure off the top of my head so I tried opening a structure (1hiv) and deleting all but CAs.  At that point it still does show ribbons and missing-segment pseudobonds, as expected.  However when I save and reopen it is only disconnected stick-dots, ribbon cannot be shown, and missing-segment pseudobonds exist but appear not to contain anything since show doesn't show any.  Attached session with both examples, model #1 after deleting all but CA atoms where it retains biopolymer info, and #2 after saving as PDB and reopening which lost PDB info.	defect	closed	high		Depiction		fixed		p.shah.lab@… Tom Goddard				all	ChimeraX
