The following automatic conversions were performed:

data item '_symmetry_cell_setting' value 'Monoclinic' was changed to
'monoclinic' 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=3D1/[s^2^(Fo^2^)+( 0.1278P)^2^+173.5518P] where =
P=3D(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=3D1/[s^2^(Fo^2^)+( 0.1278P)^2^+173.5518P] where =
P=3D(Fo^2^+2Fc^2^)/3'.
