Hi Dieter,
The surface area / volume tool (menu entry Tools -> Utilities -> Surface Area / Volume) could give buried surface areas if you ran it for the unbound receptor, unbound ligand, and then the complex, and then calculated
{ Area(receptor) + Area(ligand) - Area(receptor+ligand) } / 2
When you use this tool it reports the total area to the Reply Log (menu entry Favorites / Reply Log) and atoms are assigned an attribute saying how much area they contribute. It is a bit of a pain to run it 3 times and do the math yourself. The surface area is calculated by a web server as described in the Chimera User's Guide
http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/surfvol/surfvol.htm...
so you will need an internet connection to use it.
The Chimera User's Guide is only available in HTML as far as I know. It is written in HTML.

Hi Tom, two quick questions: 1/ can Chimera calculate/display the surface area buried by e.g. a ligand when bound on a receptor? 2/ is there a documentation other than htlm (e.g. pdf file)? Thanx, Dieter
