 Changing the _atom_site_occupancy data item value from '.' to '1'
 for all fully occupied atom sites.

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.

Automatic conversion script
Id: cif_fix_enum 1527 2010-12-29 10:47:43Z saulius 

The following automatic conversions were performed:

'_atom_site_thermal_displace_type' tag value 'Uij' was replaced with
'Uani' value 11 times.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value '1/[\s^2^(F) + 0.001F^2^]' was
changed to 'calc'. New tag '_refine_ls_weighting_details' was
created. The value of the new tag was set to 'w = 1/[\s^2^(F) +
0.001F^2^]'.
