[Chimera-users] display of improper peptide bond

Hi, I am trying to get rid of an improper bond that chimera is displaying between two nearby segments that are actually cleaved. The bond is distorted, creating long CACB bonds if B-spline mode is active. I tried to turn off the auto-chaining, but didn’t work. Because PYmol can properly display these segments as independent polypetides, I was wondering if there is other adjustment that I can try before manually deleting the bond. The PDB is 1ohf and the bond is between residue 570 and 571. Cheers,
