public interface Structure
extends java.lang.Cloneable, java.io.Serializable

Interface for a structure object. Provides access to the data of a PDB file. A structure object allows to access the PDB header information as well as to the data from the ATOM records. The header information is currently available through the following objects:

The structure object provides access to the data from the ATOM records through a hierarchy of sub-object:

 Structure
         |
         Chain
             |
             Group
                 |
                 Atom

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

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

A:

  Structure loadStructure(String pathToPDBFile){
                PDBFileReader pdbreader = new PDBFileReader();

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

Q: How can I calculate Phi and Psi angles of AminoAcids?

A:

  void calcPhiPsi(Structure structure){


                // get the first chain from the structure

                Chain chain  = structure.getChain(0);

                // A protein chain consists of a number of groups. These can be either
                // AminoAcid, Hetatom or Nucleotide groups.
                //
                // Note: BioJava provides access to both the ATOM and SEQRES data in a PDB file.
                // since we are interested in doing calculations here, we only request the groups
                // from the ATOM records

                //  get the Groups of the chain that are AminoAcids.
                List groups = chain.getAtomGroups(GroupType.AMINOACID);

                for ( int i=0; i < groups.size(); i++){

                        // since we requested only groups of type AMINOACID they will always be amino acids
                        // Nucleotide and Hetatom groups will not be present in the groups list.

                        b = (AminoAcid)groups.get(i);
