The following automatic conversions were performed:

'_geom_bond_publ_flag' value 'Y' changed to 'y' according to the
built-in table from CIF Core dictionary named 'cif_core.dic' version
2.4.1 from 2010-06-29 (2 times).

'_geom_angle_publ_flag' value 'Y'
changed to 'y' according to the built-in table from CIF Core
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29 (5

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0598P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3' was
changed to 'calc'. New tag '_refine_ls_weighting_details' was
created. The value of the new tag was set to
'w=1/[\s^2^(Fo^2^)+(0.0598P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3'.
