 The datacards to customize are three: param_card.dat, run_card.dat and Madweight_card.dat The datacards to customize are three: param_card.dat, run_card.dat and Madweight_card.dat
  
-  * param_card.dat: In this datacard it is stored the model, to change it, just replace existing values of particles mass, width, couplings. For instance, in the case of tH analysis, the Higgs boson mass has to be set to 125 and the Higgs-top coupling to -173. +  * __**param_card.dat**__: In this datacard it is stored the model, to change it, just replace existing values of particles mass, width, couplings.

-  *  run_card.dat: Information about colliding particles are stored here, proton-proton collisions are considered. The value of per-beam-energy has to be changed, default is 8 teV per beam.  +  *  __**run_card.dat**__: Information about colliding particles are stored here, proton-proton collisions are considered.

-  *  Madweight_card.dat: This is the Madweight configuration card. The first thing to change is the name of the job that is going to be submitted. Among the other parameters to set there are the number of events and the parameter of interest. Example: if the mass of the Higgs is the parameter of interests of the specific analysis, then it has to be specified in the following way: +  *  __**Madweight_card.dat**__: This is the Madweight configuration card.

 + 12   25    # Id of the particle for wich the parameter must be changed

 + 13   130 
 +</code>
  
 +  * run_card.dat and param_card.dat have to remain unchanged once the hypothesis is defined. The parameter ''name'' in Madweight_card.dat has to be changed each time the hypothesis has to be run over a different sample. It is very important to change this value because otherwise the previous results will be overwritten.
 +  * Also the lhco file has to be updated each time MadWeight has to be run over a new sample: the lhco file related to the specific sample must be placed in the Events directory and named ''input.lhco''.
