Hello,

Sorry if this is not relevant to this mailing list.

I was wondering if there are any modules available under cctbx to query PDB database programmatically.

There was an option to SQL-query PDBe (from here :http://www.ebi.ac.uk/pdbe-as/pdbedatabase/ ).  But, this service has been retired since Mar 2015.  How else could complex query on PDB possible? 

An example query could be:

list of PDBid with SCOPid="1hba" and (Resolution < 2 and R/Rfree < 15/20) or (Resolution < 3 and R/Rfree < 20/25 ) and Completeness < 95% and structureFactorAvailability="Y"
