The single data item in this category is as follows:
The bullet () indicates a category key.
Phasing of macromolecular structures often involves the application of more than one of the methods described in the PHASING section of the mmCIF dictionary, such as when phases generated from a multiple isomorphous replacement experiment are improved by molecular averaging. The PHASING category is used to list the methods that were used.
At present, the category contains a single data item, the purpose of which is to specify the method employed in the structure determination. It may have one or more of the values listed in the dictionary (Example 3.6.6.1).
