==========================================================
Please add  to this README file all information concerning 
config files, simulation, digitalization, clusterization, 
reconstruction and macro analysis

==========================================================
 How to run a MUON generation
==========================================================
aliroot
root [0] gAlice->Run(10,"$ALICE_ROOT/MUON/Config_MUON_test.C");

1 single muon of 7 GeV/c in the MUON spectrometer 
acceptance will be simulated using geant3. 
Hit information will be store in the root file in the
execution directory.
If you want to change the option or to define a new directory
for hits, you have to do the following before:
root [0] gAlice->SetConfigFunction("Config( \"/home/martinez/aliroot/work_NewIO/test/\" , \"box\" );"); 

============================================================
 How to run MUON Digitalization
============================================================
To process the digitalization of hits the AliRunDigitizer 
framework is used:

AliRunDigitizer   * manager = new AliRunDigitizer(1,1);
manager->SetInputStream(0,"galice.root");
AliMUONDigitizerv1* dMUON   = new AliMUONDigitizerv1(manager)
manager->AddDigitizer(dMUON);
manager->Exec("deb");

============================================================
 How to run MUON RecPoint clusterization
============================================================
aliroot -b << EOF
.includepath $ALICE_ROOT/STEER
.includepath $ALICE_ROOT/MUON
.L $ALICE_ROOT/MUON/MUONrawclusters.C++
MUONrawclusters("galice.root",0,9999); 
to Load
gSystem->Load("$ALICE_ROOT/MUON/MUONrawclusters_C.so")

============================================================
 How to run MUON Trigger
============================================================
.includepath $ALICE_ROOT/STEER
.includepath $ALICE_ROOT/MUON
.L $ALICE_ROOT/MUON/MUONtrigger.C++
MUONtrigger("galice.root",0,9999); 
To Load
gSystem->Load("$ALICE_ROOT/MUON/MUONtrigger_C.so")
============================================================
 How to run MUON Tracking reconstruction (old output)
===========================================================
.includepath $ALICE_ROOT/STEER
.includepath $ALICE_ROOT/MUON
.L $ALICE_ROOT/MUON/MUONrecoNtuple.C++
MUONrecoNtuple(0,9999,0,"galice.root") 
To Load   
gSystem->Load("$ALICE_ROOT/MUON/MUONrecoNtuple_C.so")
First event and last event are given by hand, but this will change.

===========================================================
 How to run MUON Tracking reconstruction (new output)
===========================================================
.includepath $ALICE_ROOT/STEER
.includepath $ALICE_ROOT/MUON
.L $ALICE_ROOT/MUON/MUONTracker.C++
MUONTracker("galice.root",0,9999);    
To Load
gSystem->Load("$ALICE_ROOT/MUON/MUONTracker_C.so")
Output in MUON.Tracks.root using the new IO 
as a TClonesArray of AliMUONTrack

============================================================
 How to run MUONCheck macro
============================================================
To check the content of a root data file, the MUONCheck
provides a ascii output on screen.

To compile MUONCheck.C
.includepath $ALICE_ROOT/STEER
.includepath $ALICE_ROOT/MUON
.L $ALICE_ROOT/MUON/MUONCheck.C++
To Load
gSystem->Load("$ALICE_ROOT/MUON/MUONCheck_C.so")

To print Kine : (default file is galice.root )
MUONkine()

To print hits : (default file is galice.root if not MUONhits("toto.root""); )
MUONhits()  

To print digits : (default file is galice.root)
MUONdigits()  

To print rawcluster : (default file is galice.root)
MUONrecpoints()

To print trigger : (default file is galice.root)
MUONTestTrigger()


============================================================
 How to check the Geometry
============================================================
gAlice->Init("$ALICE_ROOT/MUON/Config_MUON_test.C");
.L $ALICE/geant3/TGeant3/G3GUI.C
G3GUI()


============================================================
 How to run MUONdisplay
============================================================
Frist you need to perfomr a full simulation: 
generation, digitalisation and clusterisation
.L $ALICE_ROOT/MUON/MUONdisplay.C
MUONdisplay(0,"galice.root")

============================================================
 Tracking parameters, cuts, energy loss and physics processes
============================================================
Tracking parameters in MUON are automatically defined by GEANT
MUON takes the default values of CUTs  and physics processes
defined by the Config files, except for the gas mixture medium 
of the tracking chambers. The CUT's and physics processes of
the gas mixture medium  is then defined in the galice.cuts file
in the data directory. In particular ILOSS parameter MUST be
equal unity (1) in order simulate a realistic energy loss
distribution (mean value and fluctuations) in the active gas.
