   2 ALERT type 5 Informative message, check
It is advisable to attempt to resolve as many as possible of the alerts in all categories. Often the
minor alerts point to easily fixed oversights, errors and omissions in your CIF or refinement
strategy, so attention to these fine details can be worthwhile. In order to resolve some of the more
serious problems it may be necessary to carry out additional measurements or structure
refinements. However, the purpose of your study may justify the reported deviations and the more
serious of these should normally be commented upon in the discussion or experimental section of a
paper or in the "special_details" fields of the CIF. checkCIF was carefully designed to identify
outliers and unusual parameters, but every test has its limitations and alerts that are not important
in a particular case may appear. Conversely, the absence of alerts does not guarantee there are no
aspects of the results needing attention. It is up to the individual to critically assess their own
results and, if necessary, seek expert advice.
Publication of your CIF in IUCr journals
A basic structural check has been run on your CIF. These basic checks will be run on all CIFs
submitted for publication in IUCr journals (Acta Crystallographica, Journal of Applied
Crystallography, Journal of Synchrotron Radiation); however, if you intend to submit to Acta
Crystallographica Section C or E, you should make sure that full publication checks are run on the
final version of your CIF prior to submission.
Publication of your CIF in other journals
Please refer to the Notes for Authors of the relevant journal for any special instructions relating to
CIF submission.
