Dear Chimera developers You have createdt an absolutely brilliant program. I have a small question/suggestion about displaying atoms and ribbons simultaneously. When displaying a number of backbone atoms and then putting on a ribbon, then some of the atoms dissapear in release 1700 and onwards. Is there a way to avoid this behaviour? It basically means that I am stuck with the pre-1700 version, but maybe there is some parameter I can tweak to make it work in the new versions? I would be grateful for your help. I reproted this as a bug some 6 months ago, but was told that it was supposed to be like this. I measure experimental values for selected backbone atoms and display them as colorcoded spheres on top of a ribbon to indicate what is measured different places in the structure. If you have suggestions to acieve this behaviour in another way I would be grateful. Thank you in anticipation, Søren -- Søren M.
