 Changing the symmetry operation id associated with operation '1/2+X,1/2+Y,Z'
 from '144' to '145' in order to make all of the id values unique.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'w=1/\s^2^' 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^'.
