validation reports in ValidatorDB also mention various unusual aspects encountered during validation. Sometimes the processed PDB entries contain information that is ambiguous, conflicting or which deviates strongly from the expected reference. [[ValidatorDB]] reports such events as processing warnings. Such information can be found in the '''Processing Warnings''' tab on the specifics page. The selection field at the top of the page helps filter the warnings for different residues, in case more of them are in validation report. Simply click on the drop down menu and select the category of warnings that you would like to explore. Processing warnings are issues that may cause incorrect Validation, such as bad two residues being too close together ( misused concept of alternate conformations) or unusual bond lengths given by the CONECT records. Make sure that negative validation results (e.g., missing atoms) are not in fact caused by ignoring some atoms in an ill - formed structure....include degenerate...
