7// CreateDCSAliasMap() creates input that would in the same way come from DCS
8// ReadDCSAliasMap() reads from a file

26 // some fake data has to be created.
27 //
28 // The "fake" input data can be taken using either (a) or (b):
29 // (a) data from a file: Use ReadDCSAliasMap()
30 // the format of the file is explained in ReadDCSAliasMap()
31 // To use it uncomment the following line:
32 //
33 //TMap* dcsAliasMap = ReadDCSAliasMap();
34 //
35 // (b) generated in this macro: Use CreateDCSAliasMap() and its documentation
36 // To use it uncomment the following line:

45 // The shuttle can also process files that originate from DCS, DAQ and HLT.
46 // To test it, we provide some local files and locations where these would be found when
47 // the online machinery would be there.
48 // In real life this functions would be produces by the sub-detectors
49 // calibration programs in DCS, DAQ or HLT. These files can then be retrieved using the Shuttle.
50 //
51 // Files are added with the function AliTestShuttle::AddInputFile. The syntax is:
52 // AddInputFile(<system>, <detector>, <id>, <source>, <local-file>)
