MTR DA for online

Contact: Franck Manso <manso@clermont.in2p3.fr>
Link: http://aliceinfo.cern.ch/static/Offline/dimuon/muon_html/README_mtrda.html
Run Type:  ELECTRONICS_CALIBRATION_RUN (calib), DETECTOR_CALIBRATION_RUN (ped)
DA Type: LDC
Number of events needed: 100 events for ped and calib
Input Files: Rawdata file (DATE format)
Input Files from DB:
MtgGlobalCrate-<version>.dat
MtgRegionalCrate-<version>.dat
MtgLocalMask-<version>.dat
MtgLocalLut-<version>.dat
MtgCurrent.dat

Output Files: local dir (not persistent) 
ExportedFiles.dat

/*

Version 2 for MUONTRGda MUON trigger
Working version for: 

 reading back raw data

 Versionning of the Mtg file

 DA for ELECTRONICS_CALIBRATION_RUN (calib)
   checking dead channels

 DA for DETECTOR_CALIBRATION_RUN (ped)
   checking the noisy channels

 Interfaced with online database and file exchange server

November 2007
Ch. Finck

To be checked:
 Writing into the online database (need update of daqDAlib)
To be done:
 Looking at scalers outputs
