265	cartoon (ribbon) helix inside-out problems	Elaine Meng	Conrad Huang	"In the current ChimeraX it is fairly common to see places where the helix cartoon (ribbon) turns inside out.  Or to describe this another way, one edge of the ribbon should consistently track the carbonyls, but instead there is a twist so that the carbonyl edge in one part of the helix is not the carbonyl edge in another part.  

The attached ChimeraX script shows this in a couple of examples: 2mnr (see residue ranges 88-93,259-261,286-290 highlighted with color) and 2gbp (56-58,223-225,272-274).  It is not hard to find examples.  These are just some proteins I was looking at in more detail and for which I'd noted the residue numbers of the problem areas."	defect	closed	critical		Depiction		fixed		Tom Goddard				all	ChimeraX
