-How to setup the code I use on lxplus
+===== How to setup the code I use on lxplus =====
+**1. Setup RootCore and checkout the packages**
+I created all of my analysis codes at the work area (not home) on lxplus where I keep all of required data for my analysis.
+One can get my package using **svn co** as follows: ''svn co $SVNINST/Institutes/Carleton/HLT_JetTrigger
+''
+At the work area, first I should bring up ATLAS software using following command :
+''setupATLAS''
+For the first time, I needed to install //RootCore// Packages using:
+''rcSetup Base,2.4.3'' ;for the next time only ''rcSetup'' is required.
+Every time I add a new package to my header file, I should make it available for my code by typing :
+''rc find_pacakges''
+Before running my code, I should compile it using :
+''rc compile''
+**2. How to run the validation of the HLT jet building. This produces histgorams of the Reconstructed jets**
+I created a macro called //run.cxx// where I used //Samplerhandler// tool which is very useful for organizing input and output files. This macro is located at //macro// directory. To run my code, following command is required at //macro// directory :
+''root -l '$ROOTCOREDIR/scripts/load_packages.C' 'run.cxx ("run_result")'''
+Using this command, my code will be running at //root// and all of the output files (histograms) can be found at //run_result// directory.
+**3. How to make nice plots of the produced histograms**
+**Dag's test of the code**
+Logging in to lxplus, I do:
+  setupATLAS
+  cd /tmp/$USER
+  rcSetup Base,2.4.8
+  svn co svn+ssh://svn.cern.ch/reps/atlasinst/Institutes/Carleton/HLT_JetTrigger
+  rc find_packages
+  rc compile
+Compilation was successful! Now, let's try to run it
+  cd HLT_JetTrigger/macros/
+  root -b $ROOTCOREDIR/scripts/load_packages.C 'run.cxx("hlt_results")'
