PDB Reading
The read PDB methods produce a hierarchy that looks as follows: One Atom per ATOM or HETATM record in the PDB. All Atom particles have a parent which is a Residue. All Residue particles have a parent which is a Chain. Waters are currently dropped if they are ATOM records. This can be fixed. The read_pdb() functions should successfully parse all valid PDB files. It can produce warnings on files which are not valid. It will attempt to read such files, but all bets are off. When reading PDBs, PDBSelector objects can be used to choose to only process certain record types. See the class documentation for more information. When no PDB selector is supplied for reading, the NonWaterPDBSelector is used. Set the IMP::LogLevel to VERBOSE to see details of parse errors.
PDBSelector *	IMP::atom::get_default_pdb_selector ()
Hierarchy	IMP::atom::read_pdb (TextInput input, Model *model, PDBSelector *selector=get_default_pdb_selector(), bool select_first_model=true)
void	IMP::atom::read_pdb (TextInput input, int model, Hierarchy h)
Hierarchies	IMP::atom::read_multimodel_pdb (TextInput input, Model *model, PDBSelector *selector=get_default_pdb_selector())

PDB Writing
The methods to write a PDB expects a Hierarchy that looks as follows: all leaves are Atom particles all Atom particles have Residue particles as parents All Residue particles that have a Chain particle as an ancestor are considered part of a protein, DNA or RNA, ones without are considered heterogens. The functions produce files that are not valid PDB files, eg only ATOM/HETATM lines are printed for all Atom particles in the hierarchy. Complain if your favorite program can't read them and we might fix it.
void	IMP::atom::write_pdb (const Selection &mhd, TextOutput out, unsigned int model=1)
void	IMP::atom::write_pdb_of_c_alphas (const Selection &mhd, TextOutput out, unsigned int model=1)
	Write a hierarchy to a PDB as C_alpha atoms. More...
void	IMP::atom::write_multimodel_pdb (const Hierarchies &mhd, TextOutput out)
