The phrase "average structure has" is correct and usable in written English.
It can be used when discussing the characteristics or features of a typical structure in a specific context, such as architecture or biology.
Example: "In this study, we found that the average structure has a height of approximately 10 meters."
Alternatives: "typical structure possesses" or "standard structure features".
The water-refined average structure had no NOE violations greater than 0.5 Å or dihedral violations greater than 5°.
Since the basal body has intrinsic nine-fold symmetry where the nine triplets have different orientations, the resulting averaged triplet structure has isotropic resolution with no missing wedge artefacts.
The optimized structure has an average surface roughness of 1.6 nm.
The A-form reference structure has an average β dihedral angle of 165.6°, corresponding to the β trans conformation.
The A-form reference structure has an average ε dihedral angle of ∼210° calculated from four CC doublets, corresponding to an n H3′– n+1 P J scalar coupling constant of 8.2 Hz.
It is also worth mentioning that no correlation could be detected between the number of models an NMR structure has and the average inter-model RMSD value (Additional file 1: Fig. S11), thus the results are not biased this way.
As the complexity of a crystallographic model increases, the chance of approximate multicollinearity increases: atoms in disordered regions which occupy similar positions in the average structure will have very similar contributions to the structure factor equations; pseudo-symmetry can also result in similar scattering contributions from related parts of the model.
The rapid rate of conformational changes allows several transitions during the simulation time, so that simulations can be started far from the expected average structure and have the possibility of finding structures consistent with NMR spectra.
This structure has historical underpinnings.
The command structure has improved.
