procheck - locate numerical values for residue accessibility (Oct/07/2006 )

I am clueless to find data related to graph 6b (residue porperties - Secondary structure & estimated accessibility) from procheck. I need to find if a motif PXXP is exposed or not in 20,000 PDB files, but I can't find this data in .rin or .out files. I am thinking to do a perl parser to do that automatically but now I need your help to locate the numerical values for residue accessibility.

The procheck webpage is

Thank you


type parameter optimised surface into google and use the vrij university page - the program POPS will give you ASA and RSA for every residue (based on a carbon alpha only model) or use NACCESS or DSSP to get RSA and ASA from a full model.
