cwb_setveto
~~~~~~~~~~~~~~~~

|
| **Usage**
|
| This command applies post-production data qualities (cat3, hveto, pem)
  to the ROOT file produced by the `cwb_merge <#cwb_merge>`__ command. Data
  quality file lists are defined in the
  `user\_pparameters.C <#user_pparameters_002eC>`__ file.
|
| **Syntax**
|

 - ``cwb_setveto action [label/list] user_parameters_file(optional) user_pparameters_file(optional)``

 - **action**

   - label same label used by cwb_merge
   - list list the label of files already merged

 -  **user\_parameters\_file** alternative user\_parameters file (optional)
 -  **user\_pparameters\_file** alternative user\_pparameters file (optional)

 This is an example of configuration file used for post-processing of S6A background

| **Example**
|

 .. code-block:: bash

    * the input files are the merged files produced by the cwb_merge command :

       - merge/wave_*_M1.root   // reconstructed events root file
       - merge/live_*_M1.root   // live time root file
       - merge/merge_*_M1.lst   // list of merged root files

    * the vetoe files must be defined in the user_pparameters.C, for example :

      const int nvdqf=3;
      dqfile vdqf[nvdqf] = {
             {"L1", "input/L1_KW_HVETO_S6A.txt", CWB_HVETO, 0., false, false},
             {"H1", "input/H1_KW_HVETO_S6A.txt", CWB_HVETO, 0., false, false},
             {"V1", "input/V1_KW_HVETO_S6A.txt", CWB_HVETO, 0., false, false},
             {"L1", "input/S6A_OFFLINE_L1_DQCAT3SEGMENTS.txt", CWB_CAT3,  0., false, false},
             {"H1", "input/S6A_OFFLINE_H1_DQCAT3SEGMENTS.txt", CWB_CAT3,  0., false, false},
             {"V1", "input/S6A_OFFLINE_V1_DQCAT3SEGMENTS.txt", CWB_CAT3,  0., false, false}
            };

    * cwb_setveto M1
      apply hveto & cat3 data quality and produce three new ROOT files in the merge directory:

       - merge/wave_*_M1.V_hvetoLHV_cat3LHV.root
       - merge/live_*_M1.V_hvetoLHV_cat3LHV.root (same file as the one produced by cwb_merge)
       - merge/merge_*_M1.V_hvetoLHV_cat3LHV.lst (same file as the one produced by cwb_merge)

    * the output vetoed merged files contains a new boolean leaf for each veto type 

       - veto_cat3_L1
       - veto_cat3_H1
       - veto_cat3_V1
       - veto_hveto_L1
       - veto_hveto_H1
       - veto_hveto_V1

      the boolean leaf is true if the event is vetoed
