 ====== Peaksearch ======
-===== Peaksearch =====
+Peaksearch is a peak searching algorithm, part of [[software:imaged11|ImageD11]]. It can be started by typing
-Go to the newly created folder (which is still empty). Then type to the Konsole:
+    peaksearch.py
+in a terminal.
-    peaksearch.py -n ../XXX/YYY -f 0 -l 111 -d ../XXX/XXgrainm20000.edf -t &&&
+Peaksearch is used when [[processing:search_for_peaks|searching for peaks]] on the diffraction images.
-where //XXX// is a space holder for the directory and //YYY// is a space holder for the stem of the edf image files (everything before the numbers).
-//&&&// is a space holder for the intensity threshold. You can also add more than one threshold by exceeding the code by another //-t &&& -t &&& -t &&& ...//, depending on how many thresholds you want to test.
+More details on peaksearch can be found in the [[https://pythonhosted.org/ImageD11/peaksearching.html|ImageD11 user manual]].
-From now on, we call the newly created files //processed data//.

-Open [[software:imaged11|ImageD11]] by going to the folder where the //processed data// is stored. Now open the program by typing the following to the Konsole:
-    ImageD11_gui.py
-The program should open. In //ImageD11// go to //Transformation//, then //Load filtered peaks// and choose the .flt file you would like to see (You automatically should be in the right folder.).
-Then go to //Transformation// and //plot y/z//. You should see a 2D diffraction image of all the spots which passed the threshold. From now on, we call this image //diffraction plot//. You should remember, which file you opened, because ImageD11 doesn't show this anywhere.
-//ImageD11// can show only one //diffraction plot// at once. If you want to compare two (or more) //diffraction plots//, you can either save the plots (as .png file) or open a new //ImageD11// in a new tab of the Konsole.
