The Flatten Icosahedron tool works on Multiscale Models surfaces for an icosahedral capsid, not on a simple icosahedron surface. The Multiscale Models surfaces are generated from applying symmetry operations to atomic coordinates of one subunit (for example, command: open viper:1pov)
I don’t know if you or VIPERdb have atomic coordinates for a subunit that would enable you to use Multiscale Models (or even if you do, whether they are in the right orientation and position to coincide with your density map), but if so, you could create the Multiscale Models surfaces, then use Surface Color (in menu under Tools… Volume Data) to color them by the density map values, then use Flatten Icosahedron (in menu under Tools… Higher-Order Structure).
I hope this helps,

I would really like to generate a flattened icosahedron (compared to the flatten icosahedron command) from the coloured icosahedron surface. In order to get a 2D map of the colours. Is this possible somehow in Chimera? Is it otherwise possible to export the icosahedron with the coloured surfaces and try in another program (like Maya of Cinema4D?).
