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

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0699P)^2^+0.2688P] 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^)+(0.0699P)^2^+0.2688P] where P=(Fo^2^+2Fc^2^)/3'.
