Hi David, Basic display tasks can be done with the menu or with commands. For example, using the menu, you can show ribbons with "Actions... Ribbon... show" and hide the atoms and bonds with "Actions... Atoms/ Bonds... hide" Besides hiding/showing, these menus also have options for what style is used to show the ribbons and atoms. <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/representation.html> If you don't have anything selected, the Actions menu just works on the whole structure. If you select something (Ctrl-click on an atom or bond, then hit up arrow on keyboard to promote that selection to whole residues), the Actions will apply just to what is selected. You might also want to try the options in the Presets menu. There are also commands to do these same things, and in commands you can give residue numbers and chain IDs, for example: rlabel :43.a,145.b,180.b color red :30-55 It sounds like you are just starting out with Chimera, and may want to take a look at the "getting started" tutorials. Choosing "Help... Tutorials" in the Chimera menu will open a browser window with links to the tutorials. Also, the Chimera Web site has a more comprehensive "getting started" tutorial: <http://www.cgl.ucsf.edu/Outreach/Tutorials/GettingStarted.html> You can also search the manual for various topics by choosing "Help... Search Documentation" from the Chimera menu. I hope this helps, Elaine ----- Elaine C.

Hello, I am an ITL researcher, I use chimera for making a ribbon image of 1HLA molecule, and I need to mark specific residues, (by the number/ position). So far, I am unsuccessful in converting wire style to the ribbon style. Please let me know if you can help, advice or direct me to required info. David, Edelshtein SRA II UCSF ITL
