Run DSSP on a pdb file, and provide a handle to the DSSP secondary structure and accessibility.
Note that DSSP can only handle one model.
Example:
>>> p = PDBParser() >>> structure = p.get_structure("1MOT", "1MOT.pdb") >>> model = structure[0] >>> dssp = DSSP(model, "1MOT.pdb") >>> # DSSP data is accessed by a tuple (chain_id, res_id) >>> a_key = dssp.keys()[2] >>> # residue object, secondary structure, solvent accessibility, >>> # relative accessiblity, phi, psi >>> dssp[a_key] (<Residue ALA het= resseq=251 icode= >, 'H', 72, 0.67924528301886788, -61.200000000000003, -42.399999999999999)
