The following automatic conversions were performed:

'_atom_site_thermal_displace_type' tag value 'Uij' was replaced with
'Uani' value 27 times.

'_symmetry_cell_setting' value 'Triclinic'
changed to 'triclinic' according to the built-in table from CIF Core
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29.

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 'w = 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^]'.
