Examples for Molecular Structure Generation
         
 
The general strategy for setting up the molecular
structure for a combination of proteins, water,
substrates, ligands, and/or nucleic acids is:
- Split the original coordinate file into several files containing the segments. A segment is defined as a protein with one continuous polypeptide chain, a continuous protein chain, a substrate, a cofactor, a ligand, all water molecules combined, or a single nucleic acid strand.
 - Generate each segment separately.
 - If necessary, apply appropriate patches to establish covalent links between segments or within segments, such as disulfide bridges.
