Class PDBFileParser

java.lang.Object
org.biojava.nbio.structure.io.PDBFileParser
public class PDBFileParser extends Object
This class implements the actual PDB file parsing. Do not access it directly, but via the PDBFileReader class.

Parsing

During the PDBfile parsing several Flags can be set. See the setFileParsingParameters(FileParsingParameters) methods.

To provide excessive memory usage for large PDB files, there is the ATOM_CA_THRESHOLD. If more Atoms than this threshold are being parsed in a PDB file, the parser will automatically switch to a C-alpha only representation.

The result of the parsing of the PDB file is a new Structure object.

For more documentation on how to work with the Structure API please see http://biojava.org/wiki/BioJava:CookBook#Protein_Structure

Example

Q: How can I get a Structure object from a PDB file?

A: 

 public Structure loadStructure(String pathToPDBFile){
        // The PDBFileParser is wrapped by the PDBFileReader
        PDBFileReader pdbreader = new PDBFileReader();

        Structure structure = null;
        try{
                structure = pdbreader.getStructure(pathToPDBFile);
                System.out.println(structure);
        } catch (IOException e) {
                e.printStackTrace();
        }
        return structure;
 }
