Category PDBX_STRUCT_MSYM_GEN

Name:
'pdbx_struct_msym_gen'

Description:

   Data items in the PDBX_STRUCT_MSYM_GEN category record details about
   the generation of the minimal asymmetric unit. For instance, this 
   category can be used to provide this information for helical and point
   symmetry systems.   The PDBX_STRUCT_MSYM_GEN data items provide the 
   specifications of the components that constitute the asymmetric unit 
   in terms of cartesian transformations of deposited coordinates.

Example:
