imgCIF / CBF CHARACTERISTICS
- MULTIPLE (pseudo)-ASCII HEADERS and BINARY SECTIONS.
- HEADERS contain CIF DATA ITEMS from ANY CIF DICTIONARY.
- One HEADER SECTION can define MULTIPLE ARRAYS (or other binary
objects).
- 2 DATA COMPRESSION ALGORITHMS are available in Version 1. One FAST,
and the second CLOSE TO OPTIMAL. (No compression is also supported.)
- HIERARCHICAL STRUCTURING is possible through data item relationships.
(This comes from mmCIF.)
- imgCIF and other CIF dictionaries are EXTENSIBLE. (An editorial
Board has just been established to review proposals for new mmCIF
data items.)
