The following automatic conversions were performed:

'_exptl_crystal_density_meas' value '--' was changed to '?' - the
value is perceived as not measured.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0318P)^2^+10.7685P] 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^)+(0.0318P)^2^+10.7685P] where P=(Fo^2^+2Fc^2^)/3'.
