I saved the CA atoms as another pdb file, and then import it, and show atoms as sphere. ________________________________ From: lvyuan zhang <gleanerly@yahoo.com> To: chimera-users@cgl.ucsf.edu Sent: Sunday, December 7, 2008 4:42:20 PM Subject: show CA as sphere and ribbon Hi, I want show one of the CAs in a single protein chain as a sphere. But it looks like that I have to hide the ribbon to let the sphere show. Is there anyway that I can show the CA as sphere and also allow the ribbon to remain? I looked at the gallery and I didn't find anything that can help me, so here I am to ask for help from you again. Thanks first! Cheers! Luyuan
