Hi Peter, I believe what you are describing is not a bug, it is merely that by default Chimera lumps all the contacting macromolecules into a single enclosed surface. However, you can tell it to enclose sets of atoms separately as you wish. One way is to use the command "split" to make each chain a separate model. Another way (allowing you to retain the whole structure in a single model) is to use "surfcat" to define categories (the groups of atoms you want lumped together) and then "surface" those categories, for example: open 1zik rain chain surfcat achain protein & :.a surfcat bchain protein & :.b surface achain surface bchain I hope this helps, Elaine ----- Elaine C.

Hi Scooter et al, When displaying the surfaces of compound structures (e.g., 1O6K.pdb), surfaces are not displayed in the areas of intermolecular contact.
I am using Chimera v 1.6 (build 37500), Mac OSX v10.6.8. We encountered this bug with a previous version, but I don't remember the resolution
