[Biopython] Bio.PDB and Bio.SeqIO.PdbIO

[Tiago Antao]

Hi,

I am trying to get around the relationship between Bio.PDB and
Bio.SeqIO.PdbIO, lets see if I got this right:

1. Bio.PDB is quite limited in terms of what records it can parse. For
example I cannot get to SEQRES or anything related to secondary
structure (SHEET, HELIX)?

2. PdbIO allows to extract the protein sequences from SEQRES


Or, to put it another way, a generic PDB file is not completely
accessible from inside Biopython in the sense that we cannot access
some of the records (SHEET and HELIX being the examples here). Or is
there a way to get to them via Bio.PDB?

Many thanks for your help,
T
