Hi Josh, Most likely you just need to get a newer version of Chimera. The transparency command was added in version 1.7, Jan 2013. It would also be available in later versions (1.8 etc.). <http://www.rbvi.ucsf.edu/chimera/docs/relnotes/1.7.html> If you use the Help menu in Chimera the documentation should match your downloaded software, but documentation on the Web might be for a different version of Chimera than what you downloaded. I hope this helps, Elaine ----- Elaine C.

Hi,

My name is Josh Carter and I am an undergraduate researcher working at Montana State University. I am using chimera to make a movie a a protein complex interaction and I'm having trouble with the transparency command. When I type in just the command into chimera it doesn't even recognize it as a command. surftransp works but transp or transparency aren't recognized. Is there a bug fix I can run for this?

Thanks, Josh
