[BioPython] Problem with Bio.PDB documentation for HSE

[Peter]

Actually...

Shameer was trying to use this HSE code:
>> #!/usr/bin/python
>> from Bio.PDB import *
>> parser = PDBParser()
>> structure = parser.get_structure('str1', '1crn.pdb')
>> model=structure[0]
>> hse = HSExposure()
>> exp_ca = hse.calc_hs_exposure(model, option='CA3')
>> exp_cb = hse.calc_hs_exposure(model, option='CB')
>> print exp_ca[100]

I replied:

I've realised that Shameer's code looks like it was based on page 12 of 
the "The Biopython Structural Bioinformatics FAQ" (i.e. the guide to 
Bio.PDB), http://biopython.org/DIST/docs/cookbook/biopdb_faq.pdf

Thomas - it looks like the documentation needs updating here. As far as 
I can tell, the source is not in CVS...
