-==== How to access the event ====+From Stripping 13 on, you have to do something like: 
 + 
 +<code python> 
 +from StrippingSelections.Utils import buildStreams 
 +streams = buildStreams('Stripping13'
 + 
 +for stream in streams: 
 +    if(stream.name() == "Calibration"): 
 +    print stream.name(), "\t", stream.outputLocations() 
 +    for line in stream.lines : 
 +        print line.name(), "\t", line.outputLocation() 
 +</code> 
 +===== How to access the event =====
 To access the event, you have to set the correct path, f.ex:  To access the event, you have to set the correct path, f.ex: 
 <code python> <code python>
 MyParticles = DataOnDemand(Location = '/Event/Dimuon/Phys/DiMuonIncLine') MyParticles = DataOnDemand(Location = '/Event/Dimuon/Phys/DiMuonIncLine')
 </code> </code>
 +or you can set the ''RootInTES'' ...
 +<code python>
 +MyParticles = DataOnDemand(Location = 'Phys/DiMuonIncLine')
 +MyGaudiSequence.RootInTES = "/Event/Dimuon"
 +</code>
 +Note that you should not set ''RootInTES'' in the stripping, as it can cause problems (but can be useful for debugging sometimes).
  
 +===== How to test stripping lines on the GRID ===== 
 +First you have to make sure, the SDSTs as well as the RAW files are accessible and are staged in (as in the test-samples). 
 +In ganga then you can do the following (in addition to the usual things): 
 +<code python> 
 +j.inputdata = DaVinci().readInputData('/someDirectory/something_SDST.py'
 +j.inputdata.depth = 2 
 +</code> 
 +where it is crucial that you set ''j.inputdata.depth = 2'' to make sure the RAW files can be accessed.
