The following automatic conversions were performed:

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

data item '_refine_ls_weighting_scheme' value 'w = 1/[\s^2^(Fo) +
0.00000|Fo|^2^]' was changed to 'calc'. A new data item
'_refine_ls_weighting_details' was created with the value set to 'w =
1/[\s^2^(Fo) + 0.00000|Fo|^2^]'.
