40// This macro is interface with AliRawReader for RAW
41// The different stucture of the patload are readout and stored in TClonesArray
42// with AliMUONRawStreamTrigger classe.
43// The macro just simpy read again the TClonesArray contents.
44// The parameter of each structure could be seen in the container classes
45// AliMUONDarcHeader, AliMUONRegHeader, AliMUONLocalStruct.
46// The class AliMUONDDLTrigger manages the structure containers.
47// The number of structures in the rawdata file could be set.
