The following automatic conversions were performed:

data item '_chemical_melting_point' value 'not measured' was changed
to '?' -- the value is undefined or not given.

data item '_atom_sites_solution_primary' value 'Other' was changed to
'other' in accordance with the
/home/data/users/saulius/crontab/automatic-downloads/current/ACS/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.
