**The DecodeAndSortAll program is used to convert data recored by different modules one run into a ROOT file. The user's physical analysis is based on the ROOT file generated by this program. The data generated by this program has been arranged in ascending order of timestamp.**


The user first needs to modify the definition in the **UesrDefine.hh** file


.. code:: cpp

  // #define ONLYPHA
  // #define ONLYPSD
  // #define ONLYZLE
  // #define ONLYSCOPE


If all modules in the DAQ only use one type of firmware, enable the corresponding definition. If there is no definition of a single firmware, the output data file will default to supporting all types of firmware.


.. code:: cpp

  #define ROOTFILEPATH "./"       //the path of ROOT file
  #define ROOTFILENAME "data"     //the name of ROOT file
  // The path and file name for ROOT files


  
.. code:: cpp

  #define RAWFILEPATH "/home/wuhongyi/"      //Path of raw data
  #define RAWFILENAME "data"                 //The file name of the raw data
  #define MODNUMBER 2                        //Number of modules used in the chassis
  const unsigned short SamplingRate[MODNUMBER] = {500, 125};//Specify the sampling rate of each modules separately; 125/500/1000 sampling rates; 0 to skip the module
  const unsigned short Firmware[MODNUMBER] = {2, 0};//DPP_PHA=0 DPP_ZLE=1 DPP_PSD=2 DPP_DAW=3 OPEN=4 Scope=5
  // Specify the firmware type for each module. If the type is specified incorrectly, there will be issues decoding the data



After modification, execute the following command to compile the program:
  
.. code:: bash
	  
  make clean
  make


After successful compilation, an executable file **decodeandsort** will be generated, and the program will run as follows:

.. code:: bash

  ./decodeandsort [RunNnumber] 

Among them, *[RunNnumber]* is the running number of the file you want to convert.
