The following automatic conversions were performed:

data item '_refine_ls_weighting_scheme' value 'calc
w=1/[s^2^(Fo^2^)+( 0.1256P)^2^+11.2328P] 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^)+(
0.1256P)^2^+11.2328P] where P=(Fo^2^+2Fc^2^)/3'.
