==Wrong chirality==
'''ValidatorDB''' and '''MotiveValidator''' present the results of several kinds of ''chirality'' analyses. If an issue is found, the following types of results are reported:
** '''Wrong chirality (Carbon)''': the chirality error was found on an sp3 hybridized carbon atom.
** '''Wrong chirality (Planar)''': the chirality error was found on a planar chiral center. Because of their spacial distribution, planar chiral centers are very sensitive even to small perturbations in the position of the substituents. Therefore, some of the errors reported here might not be significant.
** '''Wrong chirality (Metal)''': the chirality error was found on a metal chiral center. 
** '''Wrong chirality (High order)''': the chirality error was detected on a chiral atom (e.g., phosphorus) where at least one substituent is bound by a bond of higher order. 
** '''Other''': Additional chirality issue which could not be listed in any of the above categories (e.g., chirality issues on nitrogen atoms). These appear rarely in the Protein Data Bank (<0.5% of molecules).

If any issue is detected on any atom during any ''chirality'' analysis, the molecule is marked as having ''wrong chirality'', because there is at least one atom in the validated molecule with different chirality than the corresponding atom in the model. If more atoms in a molecule exhibit the same type of chirality issue, the validated molecule is counted only once in each type of statistics (e.g., if 3 carbon atoms in one glucose molecule have wrong chirality, this glucose molecule will contribute only once to the statistics on "wrong chirality (carbon)"). If a validated molecule exhibits issues in more than one type of ''chirality'' analysis, it will be counted once in each corresponding statistics (e.g., heme molecules may appear both in the statistics for ''wrong chirality (planar)'', and for the ''wrong chirality (metal)'').
