3. Simulation
-------------
VertexMacro.C. The output of the primary vertex finder will eventually be
incorporated in the tracking algorithms.
+
+10. ITS tracking version 1
+--------------------------
+
+ In order to run the TPC-ITS track matching version 1 you have to
+execute the script ITStestV1.sh. At the end of the procedure you can use the
+macro ITSPlotTracks.C to show plots of efficiency and track parameter
+resolution. An example of read-out of track parameters can be found in the
+macro ReadITSTracks.C. Specific questions about tracking V1 and its use/results
+must be addresses to Angela Badala' (angela.badala@ct.infn.it) and Giuseppe
+Pappalardo (giuseppe.s.pappalardo@ct.infn.it).
+
+
+11. ITS tracking version 2
+--------------------------
+
+ In order to run the TPC-ITS track matching version 2 you have two
+possibilities:
+
+
+ 1) run the following macros in a sequence under ITS:
+
+ AliTPCtest.C
+ AliITStestV2.C
+ AliITSPropagateBack.C
+ AliTPCPropagateBack.C
+
+ or
+
+ 2) run the macro:
+
+ AliBarrelReconstruction.C
+
+ after having created digits for TPC and ITS.
+
+Specific questions about tracking V2 and its use/results must be addresses to
+Iouri Belikov (jouri.belikov@cern.ch).
