The issues of representing single-state and multiple-state models also impact the representation of biomacromolecular structures based on cryoEM, X-ray crystallography, FRET, chemical cross-linking data, and other experimental methods. Issues of data structures needed to represent these models and data are analogous to those discussed above for solution NMR data. However, their details are beyond the scope of this perspective. Ensuring consistency in representing multiple conformational states modeled from various experimental and computational methods is critical for developing integrated structural biology methods and advancing dynamic modeling techniques.
