The following automatic conversions were performed:
'_symmetry_cell_setting' value 'Orthorhombic' changed to 'orthorhombic'
according to '/home/saulius/struct/CIF-dictionaries/cif_core.dic'
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29.

Automatic conversion script
Id: cif_fix_enum 1527 2010-12-29 10:47:43Z saulius 

The following automatic conversions were performed:

'_cell_measurement_temperature' value 'room temperature' was changed
to '295(2)' - the room/ambient temperature average [293;298] in
Kelvins(K) was taken.

'_diffrn_ambient_temperature' value 'room
temperature' was changed to '295(2)' - the room/ambient temperature
average [293;298] in Kelvins(K) was taken.

'_chemical_melting_point'
tag was changed to '_chemical_temperature_decomposition' since the
value had been '453 (decompose)'. The value '453 (decompose)' was
changed to '453'.
