    Thank you for your video. Your sample picture is clean. What should I do to deal with dirty background? Some background area is even stronger than the band.

    • @AliceritaE
      @AliceritaE  2 роки тому

      Draw an ROI on thr background and measure it.
      Then go to PROCESS/Math/Subtract (enter the value from the ROI that you measure) then click okay.
      This step should remove the background

      First normalise your data by using by using smallest value to divide all the samples. To get the first ratio.
