     134This Generic scattering calculator also supports some pdb files without considering polarized/magnetic scattering 
     135 so that the related parameters such as Up_*** will be ignored (see the Picture below). The calculation for fixed orientation uses (the first) Equation above resulting  
     136in a 2D output, whileas the scattering calculation averaged over all the orientations uses the Debye equation providing a 1D output:

     141where v<sub>j</sub>&#946;<sub>j</sub> &#8801; b<sub>j</sub> is the scattering length of the j'th atom. 
     142The resultant outputs will be displayed in the DataExporer for further uses.
