[Chimera-users] Question about background transparency

[Elaine Meng]

Hi Scott,
Tom beat me to the punch, but I'll send this anyway!

The options that start with "--" are meant to be used when starting  
Chimera from the system command line, not in the command line within  
Chimera.  It sounds like you already looked at the man page  
describing --bgopacity and other such options:
http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/options.html

How to start Chimera from the system command line is described in the  
startup man page (URL below). On Windows, instead of using the system  
command line, you could use options by editing the Properties of the  
shortcut to Chimera, also described in this man page:
http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/startup.html

On Windows, for example, if chimera was installed in the default  
location, you could add the option to the end of the startup command:
  "C:\Program Files\Chimera\bin\chimera.exe" --bgopacity

On a Mac, for example, you could enter in the terminal:
  /Applications/Chimera.app/Contents/MacOS/chimera --bgopacity

A potential hitch is that not all computers will have the hardware to  
support the option.
Best,
Elaine
