The following automatic conversions were performed:

data item '_symmetry_cell_setting' value 'TRICLINIC' was changed to
'triclinic' in accordance with the
/home/saulius/struct/COD-crude-data/automatic-downloads/DataCite-retrospective/RSC/depositions/lib/dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.2 last updated on
2011-04-26.

data item '_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0608P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3' was
changed to 'calc'. A new data item '_refine_ls_weighting_details' was
created with the value set to
'w=1/[\s^2^(Fo^2^)+(0.0608P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3'.
