I'm looking for a way (pymol, biopython / python script, or whatever) to sample from the entire pdb. I want to select pdb's with a certain attribute, a certain resolution, or rule out a certain attribute, for example membrane proteins. I also want to rule out pdb's that have metal atoms in them.

Any suggestion on how to approach this problem?

Sincerest regards.

Thanks, but doesn't have an option for heteroatoms. Any suggestions?

Another option is to use ICM Browser and there is a way there to represent all these attributes for all pdb files as atable or for a subset (created as a result of searching for certain fields). A better thing is that you can make your search more detailated and variable. For example instead of having cutoff of 2.5A for GPCR structures you can select top 5% by quality and so on.
