// The default output format of the raw data are DDL files. They are         //
// converted to a DATE file, if a file name is given as second argument.     //
// For this conversion the program "dateStream" is required. If the file     //
// name has the extension ".root", the DATE file is converted to a root      //
// file. The program "alimdc" is used for this purpose. For the conversion   //
// to DATE and root format the two conversion programs have to be installed. //
// Only the raw data in the final format is kept if the third argument is    //
// kTRUE.                                                                    //

// The methods RunSimulation, RunSDigitization, RunDigitization,             //
// RunHitsDigitization and WriteRawData can be used to run only parts of     //
// the full simulation chain. The creation of raw data DDL files and their   //
// conversion to the DATE or root format can be run directly by calling      //
// the methods WriteRawFiles, ConvertRawFilesToDate and ConvertDateToRoot.   //
//                                                                           //
// The default number of events per file, which is usually set in the        //
// config file, can be changed for individual detectors and data types       //
// by calling                                                                //

//   sim.SetEventsPerFile("PHOS", "Reconstructed Points", 3);                //
//                                                                           //
// The first argument is the detector, the second one the data type and the  //
// last one the number of events per file. Valid data types are "Hits",      //
// "Summable Digits", "Digits", "Reconstructed Points" and "Tracks".         //
// The number of events per file has to be set before the simulation of      //
