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 '_exptl_crystal_density_meas' value 'not measured' was
changed to '?' -- the value is perceived as not measured.

data item '_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.055P)^2^+1.439P] 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^)+(0.055P)^2^+1.439P]
where P=(Fo^2^+2Fc^2^)/3'.

data item '_atom_sites_solution_primary' value 'direct method' was
changed to 'direct'.
