 ## TreeWave generation
 
 This macro converts the binary file.dat acquired by the Digitizer into a ROOT file (the TreeWave.root). This file is a TTree containing in different branches all the samplings and the temperature of the signals divided for different crystals.
 
-## Create ntuple
+## Create n-tuple
 
 The second step is: `/$HOME/foot_turin/Script/PythonScript/sw_standalone/create_ntuple.py`.
 
 This class aims at processing the TreeWave.root generating the major quantities required by the analysis (amplitude, charge, baseline, fit paramters, etc.) and saving them in another ROOT file. 
 
+Enabling the fit analysis the processing time could be quite long (several minutes). Thus, the idea of the code is to run this class one time, generate the n-tuples of all the signals quantities and leave the histograms generation to the next step (read_ntuple.py).
