Hi Ajith, Yes, you can make the ribbons transparent. Please see this previous post for instructions: <http://www.cgl.ucsf.edu/pipermail/chimera-users/2006-December/001155.html

This is also done in the "similar binding sites" image tutorial: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/tutorials/convergent.html
