Connect to lxplus

ssh -Y lxplus.cern.ch -o ServerAliveInterval=240

Set the Bash shell

bash -l

Setup a CMSSW release

export SCRAM_ARCH=slc7_amd64_gcc700
cmsrel CMSSW_10_6_4
cd CMSSW_10_6_4/src
cmsenv

Connect to GitHub with SSH

The instructions to generate an SSH key can be found here. Once you have the SSH key it has to be associated with your GitHub account. If the key is not permanently added, the following should be done in every new login.

eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa
ssh-add -l

Get the latino main code

cd $CMSSW_BASE/src/
git clone --branch 13TeV [email protected]:latinos/setup.git LatinosSetup
source LatinosSetup/SetupShapeOnly.sh

Create your user configuration

cd $CMSSW_BASE/src/LatinoAnalysis/Tools/python
cp userConfig_TEMPLATE.py userConfig.py

emacs -nw userConfig.py

Replace the following line

baseDir = '/afs/cern.ch/user/x/xjanssen/cms/HWW2015/'

with your own directory,

baseDir = '/afs/cern.ch/user/[YourInitial]/[YourUsername]/cms/HWW2015/'

And add the following line

batchType = 'condor'

Get PlotsConfigurations

cd $CMSSW_BASE/src/
git clone [email protected]:latinos/PlotsConfigurations.git

Compile

cd $CMSSW_BASE/src/
cmsenv
scram b -j 10

Obtain a VO CMS certificate

The complete set of instructions can be found here. In order to obtain a VOMS certificate you must first get a personal certificate (Steps 1 and 2 of the previous link), which consists of a private and a public keys (PEM files). You can follow the personal certificates TWiki to install the certificate in your browser. Then you will need to export the certificate into a pair of PEM files, following these how to instructions. Once you have your personal certificate you can proceed with Step 3. Go to the VOMS registration page and submit a registration. Then you need to wait for an admin to confirm your registration (you will receive a notification email). Here you can find the VOMS FAQ.

To verify the expiration date of your certificate,

openssl x509 -subject -dates -noout -in $HOME/.globus/usercert.pem

To check if you can generate proxies,

grid-proxy-init -debug -verify

To check if you are a member of the CMS VO,

voms-proxy-init -voms cms

Produce a valid VOMS proxy

voms-proxy-init -voms cms -rfc --valid 168:0
cmsenv

Produce histograms

Run 2 analyses are split in 2016, 2017 and 2018. For each year there is a set of data and MC trees, together with different lepton and b-tag working points. Besides, some systematic uncertainties might change. Please go to each year to produce the corresponding histograms.

cd $CMSSW_BASE/src/PlotsConfigurations/Configurations/VH2j/Full2016_v6
cd $CMSSW_BASE/src/PlotsConfigurations/Configurations/VH2j/Full2017_v6
cd $CMSSW_BASE/src/PlotsConfigurations/Configurations/VH2j/Full2018_v6

mkShapesMulti.py \
    --inputDir=/eos/cms/store/group/phys_higgs/cmshww/amassiro/HWWNano/ \
    --doBatch=True \
    --batchQueue=workday \
    --batchSplit=Samples,Files

Check job status

condor_q

If needed, you can check the (automatically produced) configuration files of all the submitted jobs, and even submit manually some of them for debugging or test purposes.

ls $HOME/cms/HWW2015/jobs

If you need to cancel all the submitted jobs,

condor_rm [YourUsername]

Resubmit failed jobs

cd $HOME/cms/HWW2015/jobs/mkShapes__VH2j_2017
for i in *jid; do condor_submit ${i/jid/jds}; done

Group (hadd) histograms

mkShapesMulti.py \
    --inputDir=/eos/cms/store/group/phys_higgs/cmshww/amassiro/HWWNano/ \
    --doHadd=True \
    --batchSplit=Samples,Files \
    --nThreads=8 \
    --doNotCleanup

Draw distributions

In the unexpected event that you get errors drawing the distributions, it could be due to a mismatch between plot.py and samples.py. To fix them, check and remove from plot.py the proccesses that are not in samples.py.

mkPlot.py --inputFile=rootFile/plots_VH2j_2016.root --minLogC=0.01 --minLogCratio=0.01 --maxLogC=1000 --maxLogCratio=1000 --showIntegralLegend=1
mkPlot.py --inputFile=rootFile/plots_VH2j_2017.root --minLogC=0.01 --minLogCratio=0.01 --maxLogC=1000 --maxLogCratio=1000 --showIntegralLegend=1
mkPlot.py --inputFile=rootFile/plots_VH2j_2018.root --minLogC=0.01 --minLogCratio=0.01 --maxLogC=1000 --maxLogCratio=1000 --showIntegralLegend=1

To produce blinded distributions (without data) in the signal region, open plot.py and set the variable isBlind to 1 for DATA.

mkPlot.py --onlyCut=VH_2j_emu --inputFile=rootFile/plots_VH2j_2016.root --minLogC=0.01 --minLogCratio=0.01 --maxLogC=1000 --maxLogCratio=1000 --showIntegralLegend=1
mkPlot.py --onlyCut=VH_2j_emu --inputFile=rootFile/plots_VH2j_2017.root --minLogC=0.01 --minLogCratio=0.01 --maxLogC=1000 --maxLogCratio=1000 --showIntegralLegend=1
mkPlot.py --onlyCut=VH_2j_emu --inputFile=rootFile/plots_VH2j_2018.root --minLogC=0.01 --minLogCratio=0.01 --maxLogC=1000 --maxLogCratio=1000 --showIntegralLegend=1

Once the blinded distributions have been produced, don't forget to set back to 0 the variable isBlind for DATA.

Create a CERN personal website

Follow these instructions. Once the website has been created you can manage it here. In order to allow access to your website, add an .htaccess file to your www directory.

wget https://raw.githubusercontent.com/piedraj/AnalysisCMS/master/test/.htaccess

Check that it contains Options+Indexes. To improve the usability of the website add an index.php file to every directory and subdirectory.

wget https://raw.githubusercontent.com/piedraj/AnalysisCMS/master/index.php

If you have followed these steps and the website is unavailable (error 403) please open a ticket with the CERN Service Portal.

Share the results

cp -r plotVH2j_2017 /afs/cern.ch/user/p/piedra/www/.
cd /afs/cern.ch/user/p/piedra/www/plotVH2j_2017
cp ../index.php .
