 ====== Stripping ======
 ===== Idea =====
-Fill this...
+Stripping is the idea of only fully reconstructing interesting decays, which can easily be accessed afterwards. It can cause a lot of pain, though...
-==== Documentation ====
+===== Documentation =====
 A lot of documentation can be found under: https://twiki.cern.ch/twiki/bin/view/LHCb/LHCbStripping
-==== How to get the name of the lines ====
+===== How to get the name of the lines =====
 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:
   * Find out in which stream it is (Dimuon, Dielectron, EW,...)

 python
-from StrippingSelections.StreamRadiative import stream
+from StrippingSettings.Stripping12 import StreamCalibration
-locations = {} for line in stream.lines :
+locations = {}
-   locations[ line.name()] = stream.name() + ’/’ + line.outputLocation()
+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
 </code>
+  * This will give you something like: ''StrippingDiMuonIncLine Dimuon/Phys/DiMuonIncLine'', where the first one is your line and the second one the location.
+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"):
+        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:
+<code python>
+MyParticles = DataOnDemand(Location = '/Event/Dimuon/Phys/DiMuonIncLine')
+</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.
