The categories modified in the msCIF dictionary to formalize the construction of a multi-block description of modulated or composite structures are as follows:
Categories marked with ¶ are already defined in the core CIF dictionary.
Data items revised in these categories are as follows:
![[Scheme scheme37]](/schemes/Gach3o4scheme37.gif)
![[Scheme scheme38]](/schemes/Gach3o4scheme38.gif)
The core dictionary definitions of these items are revised in order to formalize the relationships between multiple data blocks representing reference and modulated structures. Guidance is provided in the msCIF dictionary on how to label data blocks in a way that makes their mutual relationships clear.
