Hi Jianghai, Some of these questions have been answered by Warren:
PyMOL doesn't show the solvent accessible surface, rather it shows the solvent/protein contact surface. The solvent accessible surface area is usually defined as the surface traced out by the center of a water sphere, having a radius of about 1.4 angstroms, rolled over the protein atoms. The contact surface is the surface traced out by the vdw surfaces of the water atoms when in contact with the protein.
PyMOL can only show solvent accessible surfaces using the dot or sphere representations:
for dots: show dots set dot_mode,1 set dot_density,3 for spheres: alter all,vdw=vdw+1.4 show spheres - Kaushik. On Monday, February 24, 2003, at 09:46 PM, Jianghai Zhu wrote:
Hi, When I used "show surface, protein", what kind of surface did I generate? Molecualr surface, accessible surface (what is the probe radius?)? How can I define the type of surface I want and the probe radius? Besides generating the surface by itself, could pymol read other surface files? like msms format, grasp format, etc. Thanks.
