IUCr CIF VALIDATION
Validation of CIF's According to IUCr Standards
This option carries out the Data Validation Number (DVN) checks
outlined by the IUCr in the
autocheck list and in the
prefilter list.
The program indicates all the failures of standards criteria, and their
level of severity. Note that most journals are much less stringent in their
requirements, nevertheless it is always useful to carry out this check
to highlight any possible problems with the structural analysis.
