// //
// sim.MergeWith("background/galice.root", 2); //
// //
// The first argument is the file name of the background galice file. The //
// second argument is the number of signal events per background event. //
-// The default value for this is 1. MergeWith can be called several times //
-// to merge more than two event streams. It is assumed that the sdigits //
-// were already produced for the background events. //
+// By default this number is calculated from the number of available //
+// background events. MergeWith can be called several times to merge more //
+// than two event streams. It is assumed that the sdigits were already //
+// produced for the background events. //
+// //
+// The output of raw data can be switched on by calling //
+// //
+// sim.SetWriteRawData("MUON"); // write raw data for MUON //
+// //
+// 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 //
+// hits. Otherwise it has no effect. //
