 Here is a simple outline of what you should do: Here is a simple outline of what you should do:
   - Calibrate your experiment. This should be done with either [[software:​dioptas|Dioptas]] or [[software:​fit2d|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. This should be done with either [[software:​dioptas|Dioptas]] or [[software:​fit2d|Fit2D]]. Beam centers and detector distances you find in Dioptas or Fit2D will be used at a later stage of the processing.
 +  - Understand the [[dac_experiments:​geometry|concept of an O-Matrix]] and figure out your own.
   - 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. You will need to use exactly the same ones on your sample images later.   - We often also calibrate [[software:​Maud|Maud]] as this point.

-     ​* ​Identify ​images ​with double diffraction (where the single-crystal diffraction from the diamond anvil acts as a secondary source) with sufficient intensity to get mixed up with data, delete them, and replace them with either the average of the two surrounding images or create an empty image,+     ​* ​[[processing:​remove_bad_images|Remove bad images]] and replace them with either the average of the two surrounding images or create an empty image,
