- How to run MUONCheck macro
+ How to dump the content of Root data files
============================================================
-To check the content of a root data file, the MUONCheck
-provides a ascii output on screen.
+To check the content of Root data files, the AliMUONData class
+provides the functions to produce an ASCII output on the screen
+which can be redirected on the file:
-To compile MUONCheck.C
-.includepath $ALICE_ROOT/STEER
-.includepath $ALICE_ROOT/MUON
-.includepath $ALICE_ROOT/MUON/mapping
-.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() or MUONkine(##,"galice.root") for the event number ##
-
-To print hits : (default file is galice.root if not MUONhits("toto.root""); )
-MUONhits() or MUONhits(##,"galice.root") for the event number ##
-
-To print digits : (default file is galice.root)
-MUONdigits() or MUONdigits(##,"galice.root") for the event number ##
-
-To print sdigits : (default file is galice.root)
-MUONsdigits() or MUONsdigits(##,"galice.root") for the event number ##

How to check the Geometry with the new Geometrical modeler
use RKUTA to get the optimal mass resolution of the
spectrometer. The choice of HELIX or RKUTA is done in the
config file when the magnetic field is defined:
- AliMagFMaps* field = new AliMagFMaps("Maps","Maps", TRACKING, FACTOR, MAXB, AliMagFMaps::k4kG);
+ AliMagFMaps* field = new AliMagFMaps("Maps","Maps", TRACKING, FACTOR, MAXB, AliMagFMaps::k5kG);
gAlice->SetField(field);
TRACKING must be 1 for RKUTA and 2 for HELIX (the default value for aliroot is 2 (HELIX))
FACTOR allows you to set the magnetic field to 0, just putting FACTOR=0. Default value is 1.

+How to check the alignment software
+==========================================================
+
+The script AlirootRun_MUONtestAlign.sh allows you to check the software for
+the alignment with physics tracks. The script will:
+- Generate a misaligned geometry in a local CDB (default FullMisAlignCDB)
+- Simulate 1000 events using previously misaligned geometry
+- Reconstruct the events using perfect geometry
+- Run the alignment code over the above events using MUONAlignment.C
+
+To run you need to type:
+$ALICE_ROOT/MUON/AlirootRun_MUONtestAlign.sh
+
+The results of the test are saved in test_align/ directory. The file measShifts.root
+contains useful graphs for studying the alignment performances. A local CDB
+containing the realigned geometry is also created (default is ReAlignCDB). The
+file $ALICE_ROOT/MUON/data/transform2ReAlign.dat contains the
+transformations describing the realigned geometry to be compared with the
+used misaligned geometry $ALICE_ROOT/MUON/data/transform2.dat.
+
+IMPORTANT NOTE: For a useful test of the alignment performances, the
+order of 100 000 tracks is needed, it is then advisable to generate and
+reconstruct enough events separately and run MUONAlignment.C providing a file list
+afterwards.

How to Merge events
==========================================================
In this example, for simplicity, only the first hit of a
hit-track is used to check the particle ID.

+Macro to process PDC06 preproduction
+==========================================================
+
+To read a generation/reconstrution from PDC06 preproduction, and write a file
+with a tree of AliMUONTrackLight / AliMUONPairLight :
+go to the directory containing the generation/reconstruction. From there run
+aliroot
+.x DecodeRecoCocktail.C+
+.q
+
+To read the file previously generated:
+aliroot
+.x ReadRecoCocktail.C+
+.q
