Dear Urszula, If you just wanted to add a bond, you can use the “bond” command, for example “bond sel” if you have selected the two atoms, <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/bond.html> …or the Build Structure tool (in menu under Tools… Structure Editing), the Adjust Bonds section <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/editing/editing.html> I hope this helps, Elaine ----- Elaine C.
