Hello Albert, You can use command “rlabel”: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/rlabel.html> Note, however, that a limitation of webgl export is that it does not include labels. To find out about Chimera features, you can search documentation, for example for “label residue” with menu: Help… Search Documentation, or you could try one of the “getting started” tutorials: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/getting_started.html> <http://www.rbvi.ucsf.edu/Outreach/Tutorials/GettingStarted.html> You could also see the command index for short descriptions of all commands: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/framecommand.html> I hope this helps, Elaine ----- Elaine C.
