[Chimera-users] Rendering protein molecule to a geometry format by Chimera

[Tom Goddard]

Hi Hsin-Yi,

  There are lots of messages on the Chimera mailing list about how to identify surface exposed residues, for example,

	http://plato.cgl.ucsf.edu/pipermail/chimera-users/2011-May/006336.html <http://plato.cgl.ucsf.edu/pipermail/chimera-users/2011-May/006336.html>

You can search the mailing list from the Chimera documentation web page:

The multiscale tool makes surfaces for each chain.  To make surfaces of any set of selected atoms use the molmap command, for example, “molmap sel 5” to make a 5 Angstrom resolution surface.  Here are molmap docs:

	http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/molmap.html <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/molmap.html>

Those surfaces can be exported as OBJ with menu File / Export Scene….

I use 'Multiscale models' tool in 'Higher-Order Structure' choice and then make the model by resurfacing at some appropriate resolution. It turns out that the whole protein molecule can be modeled pretty nicely.

I want to render the exposed residues (those residues on the surface) and non-exposed/buried residues separately, so I will have two obj files (one for the exposed residues and the others for the non-exposed residues).
