Hi Davide, There is a new command in Chimera 1.4 daily builds that lets you turn on silhouette edges and set their width set silhouette set silhouette_width 2 and to turn off silhouette edges ~set silhouette Here's the documentation http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/set.html You're right that the "ac" command to run keyboard shortcuts doesn't work in nogui mode. That is because of some sloppy code that tries to create the keyboard shortcut dialog if you use the "ac" command and dialogs cannot be created in nogui mode. I've added an entry to the Chimera request list to fix that. http://plato.cgl.ucsf.edu/trac/chimera/wiki/requests Tom -------- Original Message -------- Subject: Re: [chimera-dev] Generating images in chimera with the --nogui option From: Davide Baú To: Tom Goddard Date: 8/27/09 7:22 AM

Tom,

how are you?

I'm just back from (good) holidays! Hope you had good holidays too :-)

I've tried out the "shape tube" command and it works great. Just one question. From the sample image you attached to your last email, it seems to me that silhouettes are toggled on ('ac se'). Is that true/possible via a command script? Chimera Keyboard Shortcuts (Accelerators) do not work when called form within a script (Error while sourcing chimera.cmd: Unrecognized command: "'ac") and I haven't found a different way (maybe using the set command?) to toggle silhouettes on.

Thanks againg for your support, Davide
