Hi Fengyun, Do you have a space group with a "polar axis"? For example P21? If that's the case the shift is inconsequential: shifting the entire structure arbitrarily along a polar axis does not change the calculated structure factor amplitudes. I.e. I think you don't have to worry about the shift. Ralf
