Seemingly simple, but I can’t figure it out:
I modeled a loop in 2 alternate conformations and want to display both of the conformations in a ribbon or cartoon. The selection “show ribbon, prot and alt B” does not do the trick. The selection syntax must be correct since “color red, prot and alt B; show lines prot and alt B” works. I could show only the backbone atoms in a pinch, but that is not really what I want. Hard to imagine that this is a limitation in PyMol nobody noticed over the years.
