The code is in SVN and can be found by doing:

phansson@pcphuat27]/u1/phansson/jetmetbtag% svn co svn+ssh://

...

phansson@svn.cern.ch/reps/atlasgrp/Institutes/SLAC/FlatAna

In order to run it you need a few packages that is used:

ROOT

Root is needed.

GRL

phansson@pcphuat27]/u1/phansson/jetmetbtag% svn co svn+ssh://phansson@svn.cern.ch/reps/atlasoff/DataQuality/GoodRunsLists/tags/GoodRunsLists-00-00-84 GoodRunsLists

Compile this package:

phansson@pcphuat27]/u1/phansson/jetmetbtag% cd DataQuality/GoodRunList/cmt
phansson@pcphuat27]/u1/phansson/jetmetbtag/DataQuality/GoodRunList/cmt% gmake -f Makefile.Standalone

Copy the shared library to the topology directory where you will run your jobs (thi can be improve at some point):

phansson@pcphuat27]/u1/phansson/jetmetbtag/DataQuality/GoodRunList% cp ../Standalone/libGoodRunsList.so ../../FlatAna/trunk/topologies/jetmetbtag/

JES uncertainty provider package:

phansson@pcphuat27]/u1/phansson/jetmetbtag% svn co svn+ssh://phansson@svn.cern.ch/reps/atlasoff/Reconstruction/Jet/JetUncertainties/tags/JetUncertainties-00-01-02 JetUncertainties

This package will be compiled on the fly by FlatAna but you need to copy the root file to the topology directory:

phansson@pcphuat27]/u1/phansson/jetmetbtag% cp JetUncertainty/JESUncertaintyProvider/share/JESUncertainty.root FlatAna/trunk/topologies/jetmetbtag/

Trigger Navigation Tools:

phansson@pcphuat27]/u1/phansson/jetmetbtag% svn co svn+ssh://phansson@svn.cern.ch/reps/atlasoff/Trigger/TrigAnalysis/TriggerMenuNtuple/tags/TriggerMenuNtuple-00-01-32 TriggerMenuNtuple

This package MUST be compiled first!

phansson@pcphuat27]/u1/phansson/jetmetbtag% cd TriggerMenuNtuple/cmd

Edit the Makefile in this directory.  You must remove the two instances of "-m32" lines 15,20.

phansson@pcphuat27]/u1/phansson/jetmetbtag/TriggerMenuNtuple/cmd% make

you might need to check that the path to this package are correct in ana.C (your run directory e.g. topology/jetmetbtag/), in particular check a few hard-coded paths (not very nice):

gSystem->AddIncludePath(" -I../../../../DataQuality/GoodRunsLists/");

gSystem->AddIncludePath(" -I../../../../JetUncertainties/");

gSystem->CompileMacro("../../../../JetUncertainties/src/JESUncertaintyProvider.cxx","k");

gSystem->AddIncludePath(" -I../../../../TriggerMenuNtuple");

gSystem->Load("../../../../TriggerMenuNtuple/lib/libTriggerMenuNtuple.so","k");

Run an example

In order to run on the example you need a ntuple. This example runs on ntuples in e.g.an ntuple:
/u1/data/user09.DavidWilkinsMiller.trigger.v02.SethCaughron.misal1_mc12.EnhancedBias_1031.digit.RDO.v13004004_AANT_PHCOPY_SLIM/
If you run on pcphuat27 then you don't need to manipulate the filelists as described below: user.bcbutler.susySlim11.v1.simple_Bb_B200_L100_herwigpp_susy.merge.NTUP_SUSY.e636_s933_s946_r1831_r1700_p364/

Make sure you manipulate the filelist: 

1. Open flatana/filelist/filelist.txt and change the path (top line) and directory/path name to match your own paths.
2. e.g.: change top line-> "/u1/data/"
3. find the line: "BbB200L100.susy011      1.0             13.0                            usr/p/phansson/data/user.bcbutler.susySlim11.v1.simple_Bb_B200_L100_herwigpp_susy.merge.NTUP_SUSY.e636_s933_s946_r1831_r1700_p364/" 
4. And change it to: "BbB200L100.susy011      1.0             13.0                            user.bcbutler.susySlim11.v1.simple_Bb_B200_L100_herwigpp_susy.merge.NTUP_SUSY.e636_s933_s946_r1831_r17\
   BbB200L100.susy011      1.0             13.0                            user.bcbutler.susySlim11.v1.simple_Bb_B200_L100_herwigpp_susy.merge.NTUP_SUSY.e636_s933_s946_r1831_r1700_p364/"

All the needed compilations are done automatically in the main root macro ana.C.There is an example in the topologies/example/ directory to start from:
[ The analysis class Topology_cutflow can be run with:

[phansson@pcphuat27]/u1/phansson/jetmetbtag% cd

...

 FlatAna/trunk/topologies/

...

jetmetbtag        

[phansson@pcphuat27]/u1/phansson/

...

temp/flatana_test/FlatAna/trunk/topologies/

...

jetmetbtag% root -l        

root [0] .L ana.C

root [1] ana("cutflow","BbB200L100.susy011",100)

This should produce root files containing some basic histograms and a log file with event statistics. Have a look at the next section to get more info on what was going on and how to use a generic ntuple.

...

1. Find the line /***** ADD YOUR OWN NTUPLE TYPE BELOW and make sure that your new FileEvent class is compiled.
2. Find the line /***** ADD YOUR OWN FILEEVENT NTUPLE FORMAT BELOW *****/ and make sure that your FileEvent class is loaded (the string in the file list name given as argument is used to determine what file type should be used)
