Hi Thomas, PyMOL can detect cavities and voids on its own. From the upper control window, select Settings > Surface > Cavities and Pockets and then show your object or selection as surface, which will show the cavities as surface, not the outer molecular surface. If you need a properly vetted

Hi, Tom, have a look at MSPocket: http://appserver.biotec.tu-dresden.de/MSPocket/ It uses MSMS to generate protein solvent excluded surface (SES) and then detects pockets on the SES. It also calculates the volume for cavities (internal pockets buried in proteins) based on the SES. cheers, hongbo

Dear Pymol users, I want to display clearly the volume of a buried cavity inside my protein. Does anybody know how to do this? I've tried CastP and Caver plugins already, but they do not produce exactly the volume I want to display. I would greatly appreciate any advice. thanks, Tom -

Hi Björn, The command you're issuing, > cmd.pseudoatom('grid', pos=[i,j,k], color='white') is asking PyMOL to create an object called 'grid' -- which on subsequent calls will just append the pseudoatoms to original 'grid' object created from the first call. If you want, say 10, individual objec

Hi, I would like to generate a bounding box (grid) of pseudoatoms. I do this by the following command: cmd.pseudoatom('grid', pos=[i,j,k], color='white') My problem is, that from step to step, the algorithm slow down. I think that in each step pymol build up a new object. But he should only
