IMPORT

Import["file.cif"] reads a CIF file and returns its contents as a list of rules.

Import["file.cif", elem] imports the specified element from a CIF file.

Import["file.cif", {{elem₁, elem₂, ...}}] imports multiple elements.

The import format can be specified with Import["file", "CIF"] or Import["file", {"CIF", elem, ...}].

ImportString supports the CIF format.
