[Biopython] Mining the PDB header

[Ahmad Abdelzaher]

Hey guys,

Unfortunately  I read this in the FAQ page:

" If you are interested in data mining the PDB header, you might want
to look elsewhere because there is only limited support for this."

So if I can't do it with biopython, what other alternatives do I have?
I'm doing some PDB mining and I'm interested to retrieve the
classification of the structure, to do some clustering analysis later.

Cheers.
