Hi Hernando, There are two ways to go about this. One is to use the color command http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/color.html say 20 times in a script to gradually increase the transparency to 1. You can specify the color as 4 values r,g,b,a in Chimera 1.4 daily builds (but not in 1.3). A second approach is to download a plugin called "Animation Commands" from the Chimera Experimental Features web page (near the bottom): http://www.cgl.ucsf.edu/chimera/experimental/experimental.html Installing this gives you the "transition" command which can fade transparency. http://www.cgl.ucsf.edu/chimera/experimental/transition/transition.html Tom hsosa@aecom.yu.edu wrote:
Hi,
Is there a command to control the transparency of a ribbon representation or the whole model ?. I'm trying to fade in an out a molecule (in ribbon + wire atom representation) in movie.
Thanks
Hernando
