Switch to the "Preprocessing" tab and Select a point range as "Reference Points". It can be performed by manually inserting the values (usually around a peak) in the corresponding field or by clicking in the adjacent button and select selecting the area direcly in the plot by draggin the vertical lines. The best range is usually located around a "unique" point sequence in the plot (that can be easily distinguished from its neighbours), as the case of peaks.

Next, you will need to select the "Input WindowsWindow" , which is the interval range in the other traces that the tool will try to match with the reference window by shifting it until the SAD is reduced. The best ideal value for this field can be determined by adding more traces to the plot and checking if all of then would fit the selected trace shape in the "Reference Points " window would fit in this range for all other traces after shifting:.
