Automatic conversion scripts had previously changed 
'_atom_site_refinement_flags' tag values 'd' into 'D' as recommended by 
'cif_core.dic' version 2.4.1. However, manual inspection revealed that the 
underlying problem was actually related to a wrong tag names inside the 
atom site loop. The following changes were performed to resolve the problem: 

* '_atom_site_refinement_flags' tag was changed to '_atom_site_calc_flag'
* '_atom_site_calc_flag' tag was changed to '_atom_site_site_symmetry_order'
* '_atom_site_disorder_group' tag was split to 
  '_atom_site_refinement_flags_occupancy' and 
  '_atom_site_refinement_flags_posn'.

The following automatic conversions were performed:
'_symmetry_cell_setting' value 'Orthorhombic' changed to 'orthorhombic'
according to '/home/saulius/struct/CIF-dictionaries/cif_core.dic'
dictionary named 'cif_core.dic' version 2.4.1 from
2010-06-29.
