The following automatic conversions were performed:

'_symmetry_cell_setting' tag value 'Monoclinic P' was replaced with
'monoclinic' value as specified in the replacement file
'/home/robertas/cod-tools/perl-scripts/inputs/replacement_values.lst'.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0995P)^2^+1.2406P] 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^)+(0.0995P)^2^+1.2406P] where P=(Fo^2^+2Fc^2^)/3'.
