This is an old revision of the document!
Stripping is the idea of only fully reconstructing interesting decays, which can easily be accessed afterwards. It can cause a lot of pain, though…
A lot of documentation can be found under: https://twiki.cern.ch/twiki/bin/view/LHCb/LHCbStripping
To know how to access your line in your options file, you have to know the name of it. To find this out, do the following:
SetupProject DaVinci vXrYpZ python from StrippingSettings.Stripping12 import StreamCalibration locations = {} for line in StreamCalibration.stream.lines : locations[ line.name()] = str(StreamCalibration.stream.name()) + '/' + str(line.outputLocation()) for line, loc in locations.iteritems() : print line, loc
StrippingDiMuonIncLine Dimuon/Phys/DiMuonIncLine
, where the first one is your line and the second one the location.To access the event, you have to set the correct path, f.ex:
MyParticles = DataOnDemand(Location = '/Event/Dimuon/Phys/DiMuonIncLine')
or you can set the RootInTES
…
MyParticles = DataOnDemand(Location = 'Phys/DiMuonIncLine') MyGaudiSequence.RootInTES = "/Event/Dimuon"
Note that you should not set RootInTES
in the stripping, as it can cause problems (but can be useful for debugging sometimes).
