The following automatic conversions were performed:

'_symmetry_cell_setting' value 'Rhombohedral' changed to
'rhombohedral' according to
/home/saulius/struct/CIF-dictionaries/cif_core.dic dictionary named
'cif_core.dic' version 2.4.2 from 2011-04-26.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.3533P)^2^+347.0802P] 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^)+(0.3533P)^2^+347.0802P] where P=(Fo^2^+2Fc^2^)/3'.
