[Chimera-users] Edge lengths of virus particles

Hello Elaine, I am trying to find the edge lengths of virus particles using Chimera. The method I came up with is to 1. Create an icosahedron with the diameter of the virus. 2. Create two atoms that sit on adjacent vertices of the icosahedron 3. Measure the distance between the two atoms But this method gives me the edge length of the icosahedron and not the virus itself. Is it possible to get the edge lengths of the actual virus without having to go through this process? Thank you Vamsee
