The following automatic conversions were performed:

'_chemical_melting_point' value 'n/a' was changed to '?' - the value
is undefined or not given.

'_symmetry_cell_setting' value 'Monoclinic' changed to 'monoclinic'
according to
/usr/data/users/saulius/crontab/automatic-downloads/current/ACS/lib/dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.2 from 2011-04-26.

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