The following automatic conversions were performed:

data item '_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.1872P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3' was
changed to 'calc'. A new data item '_refine_ls_weighting_details' was
created with the value set to
'w=1/[\s^2^(Fo^2^)+(0.1872P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3'.
