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

The following automatic conversions were performed:

'_chemical_melting_point' value '422-423' was changed to '422.5(5)' -
the average value was taken and precision was estimated.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0700P)^2^] 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^)+(0.0700P)^2^]
where P=(Fo^2^+2Fc^2^)/3'.
