TopTreeProducer

Aims & design

TopTreeProducer should produce a "light" TTree which will be a subset of PAT-uples.
Running over the TopTree should be the last step before making final plots.

Aims:

Running other all datasets quickly to study the selection
Once the analysis are tuned on signal: running over signal and background to tune some parameters
Producing the "final plots"

Design:

Create one class per "object" & one "analyzer" to fill it
Create one branch per "objects" in the root-file

Requirements:

Code will be put on CVS
In the cff file, user can choose the input collection and turn on/off the different modules

Changelog of the development of the TopTreeProducer: TopTreeProducer_Changelog

On lxplus (at cern) to check out you need to do: cvs co -r MyTag -d TopBrussels/TopTreeProducer UserCode/TopBrussels/TopTreeProducer The -d option will put it in a correct directory to be able to compile the code.

ex: doing cvs co -r CMSSW_41X UserCode/TopBrussels/SanityChecker will checkout the latest development for 41X series.
It still possible to use tag which are linked or not to a branch:

cvs co -r v2 UserCode/TopBrussels/TopTreeProducer : last version working with "old CMSSW tag" (TtGenEvent home made)
cvs co -r CMSSW_227_TQAF_V04-08-07_v2 UserCode/TopBrussels/TopTreeProducer: version working with CMSSW_2_2_7 & TQAF V04-08-07
- REMARK One schould use TQAF V04-08-08 to have the genevent properly working!

TopTree skimmer

The TopTree skimmer is present since the CMSSW_35X_v6 tag. More information can be found in http://w3.iihe.ac.be/Indico_IIHE/getFile.py/access?contribId=9&resId=0&materialId=slides&confId=134

How to use

You can checkout the code:

cvs co -r v1 UserCode/TopBrussels/TopTreeProducer
