Hi Hai, I don't know what you mean by "click and drag in the list." Maybe you mean Ctrl-click to select the ribbon (which is one way of selecting the residue), but that should be same on Windows. If your computer does not show selection, you probably need to update the graphics driver. There are other ways to show a residue, for example command display :12.A to show residue 12 of chain A. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/display.html> <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/frameatom_spec.html> Of course, Ctrl-click selection on the ribbon to show green outline and then menu: "Actions... Atoms/Bonds... show" should also work. If you don't see the green outline, then it is probably the graphics driver problem mentioned above. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/selection.html> There are various tutorials that explain showing specific residues, for example: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/frameimages.html> <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/convergent.html> You may also be interested in the "getting started" tutorial for basics: <http://www.rbvi.ucsf.edu/Outreach/Tutorials/GettingStarted.html> I hope this helps, Elaine ----- Elaine C.

Hi, officer, I am Hai Li at university of texas working on the protein structure and function. Recently I begin to use chimera to show the protein structure. I lean that I need to click and drag a residue in the list in order to show this residue’s sidechain in chimra. However, I have windows and I tried to do the click and drag a residue but it did not work. Could you please tell me how to visualize a residue in windows? Thank you. hai Sent from Mail for Windows 10
