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 Synchr
otr
on Radiation
); however
, if you intend to submit to
Acta
Crystallographica Section C
or
E
or
IUCrData
, 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.
