Hi James, There are a few Chimera commands that let you show a icosahedral cage around a virus PDB model. Basically you use the sym command to make the virus capsid from the PDB asymmetric unit, then use the shape command to make the cage, then optionally use the meshmol command to show the cage with cylinders instead of lines. For example, open 2bbv sym #0 surf true shape icos radius 200 lattice 1,1 meshmol #2 3 color gold #3 There’s also a video showing how to make the cage for an electron microscopy map http://www.cgl.ucsf.edu/chimera/videodoc/cage/index.html <http://www.cgl.ucsf.edu/chimera/videodoc/cage/index.html> Here is the command documentation for more info about sym, shape, meshmol commands: http://www.cgl.ucsf.edu/chimera/current/docs/UsersGuide/framecommand.html <http://www.cgl.ucsf.edu/chimera/current/docs/UsersGuide/framecommand.html> Tom

A colleague of mine has told me that you have previously made available a script for displaying icosahedrally-symmetric pdb files on an icosahedron net. Would you happen to still have it? I can’t find any sign of it online…

Cheers (and thanks for your continued work on Chimera)

James
