[edit] Ntuple Software

How To Find the Code

The Ntuple code is located at http://atlas-sw.cern.ch/cgi-bin/viewcvs-atlas.cgi/groups/slac/NtupleMaker/

To check the code out with svn on the TRIUMF Teir3 

setup a athena release (for example 15.5.2) and go to your work directory
mkdir NtupleMaker
cd NtupleMaker/
cmt co -r BasicNtupleTools-00-01-08 ${SVNGRP}/Institutes/SLAC/NtupleMaker/BasicNtupleTools
cmt co -r CBNTAlgs-00-01-01  ${SVNGRP}/Institutes/SLAC/NtupleMaker/CBNTAlgs
cmt co -r DetailedNtupleTools-00-01-08  ${SVNGRP}/Institutes/SLAC/NtupleMaker/DetailedNtupleTools
cmt co -r NtupleUtils-00-01-00  ${SVNGRP}/Institutes/SLAC/NtupleMaker/NtupleUtils
cmt co -r TriggerNtupleTools-00-01-00  ${SVNGRP}/Institutes/SLAC/NtupleMaker/TriggerNtupleTools

[edit] Analysis Software

How To Find the Code

The analysis software is currently stored at TRIUMF in: ~inugent/public/ttbar/Stable_Version/ ~inugent/public/ttbar/Stable_scripts/


Instructions for Running code

1) Copy (cp -r) the code into a directory in you area, and put the scripts in a seperate directory were you want your workspace to be.

2) Modify the scripts in your workspace. The variable you may want to modify are: 

$CodeDir="~/ttbar/";  # The directory with your code
$OutputDir="/home/inugent//ttbar/workdir/"; # Your workspace
$InputDir="/data/ds02_1/inugent/Physics_900GeV/"; # The base diectory for the root files
$set="_900GeV_JETMET"; # The name of your workspace (ie workdir_XXXX)
$ntpType="_JETMET"; # The interface you want to use for the ntuples
$analysisType="[MissingET_Study]"; # The Analysis youw ant to run

3) Modify the code if wanted.

4) Go to your workspace and execute your script 

./todo_XXXX.pl

5) Go workdir_XXXX and compile the code 

source compile

6) Now submit your jobs 

 source Submit

7) When you jobs are done (you can check this with: qstat -u <username>):
