ntuple

This package contains tools for working with EDM-style ntuples. A separate CMSSW setup is foreseen, since the EDM-style ntuples need very few supporting libraries apart from the base CMSSW setup.

Contents

• CMSSW/src/FWTools/FWTools contains the wrappers for accessing the EDM objects from C++.
• Makefile is the main Makefile, supporting make setup/all/test.

Setting up the code

Clone the repo into the the $STPOL_DIR/src directory. This is needed to access the singletop polarization specific headers from $STPOL_DIR/src/headers.

1. Run ./setup.sh to set up CMSSW.

Using this library

The implementation of this library is decoupled from any code that uses it via git submodules. The advantage is that development workflow of a submodule X is not affected by the workflow of the main module or other submodules.

Cpp

To create your own code using this module in C++

1. Create a new repo using the example of https://github.com/jpata/stpol_testcode1
2. Add your newly created repo to the ntuple package as a submodule by doing git submodule add git@github.com:jpata/stpol_testcode1.git CMSSW/src/FWTools/stpol_testcode1
3. Compile your code using the standard CMSSW command scram b FWTools/stpol_testcode1

Troubleshooting

Generic help

Please always check and report the version hash of the main code and all the submodules using

git fetch origin; git log HEAD..origin/master --oneline; git rev-parse HEAD; git submodule status --recursive

If any of the submodule hashes contain a + in the beginning, you need to run

git submodule update --recursive
