Here's an example how to check muon ID histograms produced by MuonPIDChecker, that runs in Brunel:
login to
If the ROOT file has been merged from several original files,
three trend histograms are produced for every original histogram:
lxplus
SetupProject online
cd /afs/cern.ch/lhcb/group/dataquality/ROOT/Collision10/
Select a ROOT file, for example
root -l Beam3500GeV-VeloClosed-MagDown/70733/Real_Data_RecoStripping-03/90000000/BrunelDaVinci_FULL_70733_00006394.root
On afs, the root files are quickly deleted, but a backup is kept on CASTOR, use:
root -l /castor/cern.ch/grid/lhcb/dataquality/Collision10/Beam3500GeV-VeloClosed-MagDown/70733/Real_Data_RecoStripping-03/90000000/BrunelDaVinci_FULL_70733_00006394.root
(here use the nsls command to find ROOT files, e.g. nsls -l /castor/cern.ch/grid/lhcb/dataquality/Collision10/)
Open a TBrowser: by typing TBrowser b
Double click on the ROOT Files folder
Double click on the only item in the right window
Double click on the Muon folder
Double click on the MuonPID folder
Double click on the MonitorLong folder
Double click on any of the 46 histograms available:
