details of checkCIF/PLATON tests
This page provides a full listing of the tests that are carried
out when you submit your CIF to the IUCr checkCIF/PLATON service.
There is also a
prefilter
which checks for the data
necessary to carry out the validation tests.
The tests check whether the data in a CIF are internally consistent and
also whether the data meet defined standards. They have been designed
by crystallographers who have a particular knowledge and understanding
of current practices. The checking programs are constantly updated. Details
of how to use checkCIF/PLATON reports are given elsewhere.
