[Chimera-users] Icosahedral net from PDB

[Tom Goddard]

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

Here is the command documentation for more info about sym, shape, meshmol commands:
