The following automatic conversions were performed:

'_exptl_absorpt_correction_type' value 'None' changed to 'none'
according to /home/saulius/struct/CIF-dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.2 from 2011-04-26.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w=1/[s^2^(Fo^2^)+(
0.1280P)^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^)+( 0.1280P)^2^+0.0000P] where
P=(Fo^2^+2Fc^2^)/3'.
