Haciendo un analizador

En este paso vamos a hacer un analizador que corra sobre el archivo root que obtuvimos en el paso anterior (Particle Flow). En este proceso tenemos que usar la siguiente versión de CMSSW: CMSSW_3_3_6 Vamos a la carpeta src de esta versión:

cd CMSSW_3_3_6/src
cmsenv

Luego hacemos

svn co svn+ssh://andresib@svn.cern.ch/reps/cmsuniandes/Analysis/SusyAnalyzers

Al hacer esto se crea una carpeta nueva en "src" llamada: SusyAnalyzers. Entramos en esta carpeta y renombramos el directorio SusyOSLepton por SusyOSLeptoneliminable.

Luego movemos el directorio "SusyOSLepton_CMSSW_3_X" que se encuentra dentro de directorio "CMSSW_3_1_4/src/SusyAnalyzers/Tags" al directorio: "CMSSW_3_1_4/src/SusyAnalyzers/".

Hecho esto renombramos el directorio (que movimos); el nombre "SusyOSLepton_CMSSW_3_X" lo cambiamos por "SusyOsLepton". Entramos al directorio "SusyOsLepton" (que acabamos de renombrar) y vamos a la carpeta "test". En esa carpeta vamos a editar el archivo: "susyleptons.cfg.pat.py"

En ese archivo agregamos lo siguiente:

inputfile = 'file:/home/le-cabre/CMSSW_3_3_6/src/PhysicsTools/PFCandProducer/test/LM1_PF2PATandPATuple.root'

Es decir agregamos la ruta del archivo que obtuvimos al hacer Particle Flow. Luego vamos a la carpeta: "SusyOSLepton"

En mi caso tendría que hacer:

cd /home/le-cabre/CMSSW_3_3_6/src/SusyAnalyzers/SusyOSLepton

y compilamos

scram b -j 4

Obtenemos algo similar a lo siguiente:

una vez compilamos corremos el analizador

cd test/
cmsRun susyleptons.cfg.pat.py

deberiamos obtener algo como lo siguiente:

Al final se debe de obtener un archivo llamado "OSLepton_LM0.root". Al abrirlo con root se deberían ver varios histogramas. En principio tenemos que modificar el código del analizador para obtener histogramas de nuestro interes.

El siguiente paso es: Correr todo el proceso en GRID
