20 /// \brief The macro writes a new GRP/CTP/Config trigger configuration file
21 /// from the GRP/CTP/MUON.cfg trigger descriptor, corresponding to a
22 /// run where only MUON is used as a trigger detector.
24 /// The macro writes a new GRP/CTP/Config trigger configuration file
25 /// from the GRP/CTP/MUON.cfg trigger descriptor, corresponding to a
26 /// run where only MUON is used as a trigger detector. The
27 /// compatibility is check against the Config.C used in the simulation
28 /// (which means that the MUON detector must be there). When "check"
29 /// is "true", the macro only shows the last CTP configuration stored in
31 /// This is necessary because at the first step of the simulation (digits)
32 /// the trigger configuration is guessed from the detectors defined in the
33 /// Config.C, while the reconstruction is performed in a second separate
34 /// step, having no more knowledge of the Config.C file.
35 /// This has to be done before starting the simulations, only once after
36 /// the installation of AliRoot:
39 ///.L $ALICE_ROOT/MUON/UpdateCDBCTPConfig.C+
40 /// UpdateCDBCTPConfig(1); // just checking
41 /// UpdateCDBCTPConfig(); // update the GRP/CDB entry
44 /// AliRoot comes with a default entry corresponding to a pp trigger. In
45 /// this case, at the reconstruction phase error messages will appear (without
46 /// breaking the reconstruction): \n
48 /// E-AliCentralTrigger::CheckTriggeredDetectors: Wrong cluster mask from trigger
49 /// classes (7ffff), expecting (20c00)! Loaded trigger configuration is possibly wrong!
