Multiple Methods: Atomic structures substantially underpinned by more than one experimental method currently supported by the PDB archive (NMR, 3DEM, or crystallography/diffraction) with or without some additional data provided by currently unsupported methods.
Integrative Methods: Atomic structures with all data coming from currently unsupported methods by the PDB, or only partially underpinned by an experimental method currently supported by the PDB, or partially/entirely non-atomic structures supported by the PDB-IHM.
