=Incomplete structures=
Validated molecules exhibiting an error in at least one of the ''Completeness'' analyses are denoted as ''incomplete'', whereas the remaining molecules are reported as ''complete''. ''Incomplete structures'' refer to molecules which lack some atoms, or whose structure is significantly distorted in comparison to the model:
* '''Missing atoms''': An atom in the model has no corresponding atom in the validated molecule.
* '''Missing rings''': At least one missing atom originates from cycles (rings). The formal distinction between ring atoms and non-ring atoms (simply denoted as atoms) is meant to allow a quick localization of potential issues in molecules containing rings, especially where atom identifiers are not useful. 
* '''Degenerate''': The molecules could not be validated due to their distorted structure, i.e. significant discrepancies between the atoms and inter-atomic bonds in the validated molecule and in the model. This generally happens when residues are overlapping in the 3D space, or some atoms appear disconnected from the rest of the structure.
