Difference: TextToNtupleParser (1 vs. 16)

Set up the environment - CDF (obsolete - included for reference)

Set up the environment - AFS

If you have a Glasgow AFS account you can set up the environment by sourcing the script v16g.sh in /afs/phas.gla.ac.uk/user/g/gkirby/public. This will then allow you to use the runFillFlatFromAscii command:

runFillFlatFromAscii teststeerFillFlatFromAscii.txt PythiaOutput.dat FlatFillATLAS.root

The first argument is the steering file - this points to the VariableTree and TreeSpec files which identify the variables that the parser will read. It is important to ensure that the correct files are pointed to and that their contents are up to date, or the flat tuple will not be correctly filled. It is convenient to use different steering files to point to different "event" TreeSpec files (e.g. for different processes). The "global" file contains metadata relevant to downstream analysis.

The second argument is the output of the PythiattH code, i.e. a text file containing the relevant event output variables.

The last argument is the name of the flat tuple that will be created.

Important notes on running the parser

• Remember to increment the number after EvInfoTree for each variable that is added to the VariableTree file. If conflicting numbers are assigned to two different variables the tool will fail to run.

• The value to the left of the colon in the VariableTree file has to match the name in the text file from the event generator, and must also match what is in the TreeSpec file. It does not have to be the same as the stuff to the right. In the downstream analysis this is used as the input variable to plotting and the neural net training. This however is the point where you are flexible in mapping the branch/leaf to that name of the varaible later.

• The stuff to the right of the colon is the branch/leaf as it appears in root.

Test environment -- ATLAS Version

Once the CDF test has been successfully completed, you can move on to building an ATLAS ntuple (with additional variables).

The relevant files can be found in:

/home/ahgemmell/NNFitter-00-00-09-Edited/NNTraining/run119

The directory specification in the files will need to be changed; if they are in the working directory, leave it out:

GeneralParameter string 1 TreeSpecEv=TreeSpecATLAStth-v15.txt
# Steering file with spec of global
GeneralParameter string 1 TreeSpecGlobal=TreeSpecATLAStth-v15.txt
# Variable tree to NTP
GeneralParameter string 1 TreeToNTPMapFile=VariableTreeToNTPATLASttHSemiLeptonic-v15.txt

You also need to add the following lines:

GeneralParameter string 1 TreeNameEvInfo=D3PD
GeneralParameter string 1 TreeNameGlobalInfo=D3PD

The thing you have to match is the name in the lines containing the string "EvInfoTree" in VariableTreeToNTPATLASttHSemiLeptonic-v15.txt

to your file.

Now the first problem I see is that the lepton inforamtion is not in EvInfoTree -- so you will need to try to figure out if it is available!

Then you wil have to add this to the VariableTreeToNTPATLASttHSemileptonic-v15.txt file. I do find that

TreeSpecATLAStth-v15.txt

has:

ListParameter SpecifyVariable:PL_SelLepton_Pt 1 Type:double ListParameter SpecifyVariable:PL_SelLepton_Phi 1 Type:double ListParameter SpecifyVariable:PL_SelLepton_Eta 1 Type:double

Note that the actual px,py,pz,e as you had are not there so you may have to make a new file with those variables.

Then you need to add the variable defintions to VariableTreeToNTPATLASttHSemiLeptonic-v15.txt

Here is an example ListParameter EvInfoTree:28 1 PL_SelLepton_Pt:PL_SelLepton_Pt/PL_SelLepton_Pt:

o For each variable you add, you need to increment the number. So EvInfoTree:28 needs to goto EvInfoTree:29 for the next varaible.

o The value to the left of the : has to match your name in your text file that you write. This does no have to be the same as the stuff to the right. Later on this is used as the input variable to plotting and the neural net training. This however is your point where you are flexible in mapping the branch/leaf to that name of the varaible later.

o The stuff to the right of the : is the branch/leaf as it appears in root. In fact if you have a root file, Alistair wrote a tool to make this file from it.

The steering file should be pointed at the evinfo, global and variable tree to ntp definitions.

This page contains instructions for setting up and using a tool to parse text files and create ntuples containing the information in them.

Set up the environment

The command

hwwcdf6.1.6.mv4_81/Hww/TRTuple/root/testFillFlatFromAscii.sh

runs the program on a text file.

The code is executed via the command:

runFillFlatFromAscii teststeerFillFlatFromAscii.txt  testFlatFillATLASl4vec.txt  testFlatFillATLAS.root

The first argument is the steering file, the second is the text file you make and the third is the output root file.

The steering file should be pointed at the evinfo, global and variable tree to ntp definitions.

For initial setup:

source ~cdfsoft/cdf2.shrc

setup cdfsoft2 6.1.6.m

cd /data/cdf04/stdenis/hww_1fb/hwwcdf6.1.6.mv4_81/

srt_setup -a

cd -

Test environment -- CDF Version

Copy the following files into a test area:

/data/cdf04/stdenis/hww_1fb/hwwcdf6.1.6.mv4_81/Hww/TRTuple/root/TreeSpecEv.txt

/data/cdf04/stdenis/hww_1fb/hwwcdf6.1.6.mv4_81/Hww/TRTuple/root/TreeSpecGlobal.txt

/data/cdf04/stdenis/hww_1fb/hwwcdf6.1.6.mv4_81/Hww/HwwMtuple/root/VariableTreeToNTP.txt

/data/cdf04/stdenis/hww_1fb/hwwcdf6.1.6.mv4_81/Hww/TRTuple/root/teststeerFillFlatFromAscii.txt

/data/cdf04/stdenis/hww_1fb/hwwcdf6.1.6.mv4_81/Hww/TRTuple/root/testFlatFillATLASl4vec.txt

Edit teststeerFillFlatFromAscii.txt so the three files have no directory spec:

GeneralParameter string 1 TreeSpecEv=TreeSpecEv.txt

GeneralParameter string 1 TreeSpecGlobal=TreeSpecGlobal.txt

GeneralParameter string 1 TreeToNTPMapFile=VariableTreeToNTP.txt

Now do:

setup neurobayes_expert

setup root v5_26_00 -q GCC_3_4_6 -f Linux+2.6

Now you can run the tool via the command

runFillFlatFromAscii teststeerFillFlatFromAscii.txt  testFlatFillATLASl4vec.txt  testFlatFillATLAS.root
