Dear Chimera Users I am fairly new to the program and I have a particular problem with the display of disulfide bonds. I have an amino acid sequence, I created a pdb-file with Expasys Swiss Model Workspace. I opened the pdb file with Chimera and coloured the ribbon structue (it looks amazing), I even did a movie of my rotating protein. But I cannot display the three disulfide bonds. Is my pdb file lacking the CONECT information? How can I include them? With Swiss PDB Viewer (Deepviewer) I can show the bonds, but somehow I cannot transfer the information to the pdb file and Chimera. I also tried manually bonding the closest cysteins by selecting Cystein residues and "bond" in the command line. How do I select the two single atoms that I want to connect? I read through former similar questions in the list server but nothing helped so far. If you can find any time helping my case, it would be greatly appreciated.
