The following automatic conversions were performed:

'_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:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0832P)^2^+2.4214P] 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^)+(0.0832P)^2^+2.4214P] where P=(Fo^2^+2Fc^2^)/3'.
