| - | - Calibrate your experiment. This should be done with either Dioptas or Fit2D. Beam centers and detector distances you find in Dioptas or Fit2D will be used at a later stage of the processing. | + | - Calibrate your experiment.

| - We often also calibrate [[software:Maud|Maud]] as this point. We will use it later to figure out the cell parameters of our sample. As you start using MAUD keep a note of the parameters you use to convert your tiff images into ESG.
