-Go to the newly created folder (which ​is still empty). Then type to the Konsole:+Peaksearch ​is a peak searching algorithm, part of [[software:imaged11|ImageD11]]. It can be started by typing 
 +    peaksearch.py 
 +in a terminal.
  
-    peaksearch.py -n ../'​directory'/'​directory stem' -f 0 -l 111 -d ../'​directory'/'​median file20000.edf'​ -t &&&​+Peaksearch is used when [[processing:​search_for_peaks|searching for peaks]] on the diffraction images.
  
-**-f** marks the number of the first image, **-l** the number of the last image. +More details on peaksearch ​can be found in the [[https://pythonhosted.org/ImageD11/peaksearching.html|ImageD11 ​user manual]].
- +
-**&&&​** 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. +
- +
-From now on, we call the newly created files //processed data//. Proceed with [[software:​imaged11|ImageD11]] ​to look at the //processed data//. +
- +
-Sometimes the algorithm does not work because it cannot read the median file. You can try to run PeakSearch without typing //-d median_file.edf//​. Sometimes this works.+
