// TFile* file = new TFile("run1.root","recreate");
// TTree* T = new TTree("Run1", "Raw data for Run1");
// and then call this method: SetUserTree(T)
// If you read all events of the file, the TTree will be automatically filled
// with data :
// while( runfile->GetNextEvent() ) ;
//
// Two different TTree structures are available, depending on the option string:
//
// opt = "arrays": [default]
//
// The TTree will have the following structure:
//
// *Br 0 :NbParFired : NbParFired/I = number of fired parameters in event
// *............................................................................*
// *Br 1 :ParNum : ParNum[NbParFired]/i = array of indices of fired parameters
// *............................................................................*
// *Br 2 :ParVal : ParVal[NbParFired]/s = array of values of fired parameters
//
// This structure is the fastest to fill and produces the smallest file sizes.
// In order to be able to directly access the parameters as if option "leaves" were used
// (i.e. one branch/leaf for each parameter), we add two aliases for each parameter to
// the tree:
// PARNAME = value of parameter if present in event
// PARNAME_M = number of times parameter appears in event
// Assuming that each parameter only appears at most once in each event, i.e. PARNAME_M=0 or 1,
// then
// root[0] T->Draw("PARNAME", "PARNAME_M")
// will histogram the value of PARNAME for each event in which it is present.
// (if the selection condition "PARNAME_M" is not used, the histogram will also be filled with a 0
// for each event in which PARNAME does not appear).
// N.B. the PARNAME alias is in fact the sum of the values of PARNAME in each event.
// If PARNAME_M>1 in some events, it is not the individual values but their sum which will
// be histogrammed in this case.
//
// Thus, if the data file has parameters called "PAR_1" and "PAR_2",
// the following command will work
//
// root[0] T->Draw("PAR_1:PAR_2", "PAR_1_M&&PAR_2_M", "col")
//
// even though no branches "PAR_1" or "PAR_2" exist.
//
//
//
// opt = "leaves":
//
// The TTree will have a branch/leaf for each parameter. This option is slower and produces
// larger files.
//
// If the option string contains both "arrays" and "leaves", then both structures will be used
// (in this case there is a high redundancy, as each parameter is stored twice).
//
// The full list of parameters is stored in a TObjArray in the list returned by TTree::GetUserInfo().
// Each parameter is represented by a TNamed object.
// In order to retrieve the name of the parameter with index 674 (e.g. taken from branch ParNum),
// do:
// TObjArray* parlist = (TObjArray*) T->GetUserInfo()->FindObject("ParameterList");
// cout << "Par 674 name = " << (*parlist)[674]->GetName() << endl;
