However, you can add bonds that are not in your input file already using the command "bond" or the "Adjust Bonds" tab in the Build Structure tool (under Tools... Structure Editing in the menu): <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/bond.html> <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/editing/editing.html> I just tried saving an image as a PS file and did not have any problems. Maybe the application you are using to show images does not show PS and does not list that format in its open dialog? That is my only idea. However, if you continue to have problems you could use "Help... Report a Bug" in the Chimera window and include all information needed to reproduce the problem, and your email if you wish a response. Best, Elaine ---------- Elaine C.

It has at least five disulfide bonds. Please tell me how can I do that???and how can I save the image as a post script file....I tried it by save as .ps file but then the save file was not there in the designated folder though other formats (eg jpeg) were easily saved....
