[Chimera-users] An oddity in ribbon.

Hi, I have an oddity when showing ribbon. When I show the loop (see figs) in ribbon I get the small thing in the middle and when I show it in atom the loop is longer. In coot the loop looks fine. Is it in the PDB? is in a chimera error? It only happens in this loop in this PDB. The same loop in other PDBs is fine. Thanks, Yehuda Halfon
