The following automatic conversions were performed:

'_chemical_melting_point' tag was changed to
'_chemical_melting_point_gt' since the value was specified 'more
than' ('>') a certain temperature. The value '> 600 K' was changed to
'600' - it should be numeric and without a unit
designator.

'_geom_bond_publ_flag' value 'Yes' changed to 'yes'
according to /home/saulius/struct/CIF-dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29 (14
times).

'_geom_angle_publ_flag' value 'Yes' changed to 'yes'
according to /home/saulius/struct/CIF-dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29 (11
times).

'_geom_angle_publ_flag' value 'No' changed to 'no' according
to /home/saulius/struct/CIF-dictionaries/cif_core.dic dictionary
named 'cif_core.dic' version 2.4.1 from 2010-06-29 (9
times).

'_geom_torsion_publ_flag' value 'Yes' changed to 'yes'
according to /home/saulius/struct/CIF-dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29 (8
times).

'_geom_torsion_publ_flag' value 'No' changed to 'no'
according to /home/saulius/struct/CIF-dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29 (14

The following automatic conversions were performed:

'_exptl_crystal_density_meas' value 'not measured' was changed to '?'
- the value is perceived as not measured.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w =
1/[\s^2^(Fo^2^)+(0.0505P)^2^+0.1474P] where P=(Fo^2^+2Fc^2^)/3' 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^(Fo^2^)+(0.0505P)^2^+0.1474P] where P=(Fo^2^+2Fc^2^)/3'.
