+===== How to import diffraction images into Maud =====
+Maud uses //.esg// file format. To convert your //.tif// diffraction image, you can either use [[software:fit2d|Fit2D]] or (in case you are not familiar with Fit2D) a plugin in Maud.
+=== Fit2D ===
+...
+=== Maud plugin ===
+  - Convert your diffraction image to //.tif// format (if it isn't already). The [[software:timelesstools|TIMEleSS tools]] may be helpful for this.
+  - Open Maud.
+  - Click on //DataFileSet_X//, then the eye, then the //Datafiles// tab, then //From images//. A new window called //Area image// should open.
+  - Click //File// and //Open//. Choose the diffraction image you want to refine (the one you converted to //.tif// earlier). A black window should appear (sometimes you can see some faint spots but usually it's pitch black).
+  - Open the properties window by clicking on //Image// and //Properties//. Change the unit to //mm// and the pixel dimensions to the right size (for example 0.2 mm for P02.2 and 0.079 mm for ID27, respectively). Press //Ok//.
+  - Click //Plugins//, then //Maud Plugins// and then //Multi-Spectra from normal transmission/reflection image//. A new parameter window opens.
+  - Type in your //sample-detector distance// and beam center (//Center X// and //Center Y//) from your calibration. Put the //Tracker circle radius// to a 2θ value which is still completely visible on your diffraction images (usually 20° is fine). Put the //Final angle// to 360° and the //Number of spectra// to 72. Leave the other values default.
+  - Click //Update//. This should move a red circle in your black screen to the center. If it has moved but not to the center you might have a type in the values entered above.
+  - Click //Ok//. A save window should open. Save the image. Make sure it gets the ending //.esg//.
+  - Close the //Area image// window. Don't save changes.
