iSpy How to make .ig files for iSpy using CMSSW

The following applies to CMSSW version 3_1_x or later

iSpy reads "ig files" containing event and detector data. These are created by running standard CMSSW analyzers, as follows:

 

1) Set-up your environment for CMSSW release X_Y_Z:

For csh:

setenv CMSSW_VERSION CMSSW_X_Y_Z

For sh:

export CMSSW_VERSION=CMSSW_X_Y_Z

2) Check out sources and build:

for CMSSW releases before 3_10_x

project CMSSW
cmsrel $CMSSW_VERSION
cmsenv
cvs co -r preCMSSW_3_10 ISpy/Services 
cvs co -r preCMSSW_3_10 ISpy/Analyzers
scram b

for CMSSW releases after 3_10_x

project CMSSW
cmsrel $CMSSW_VERSION
cmsenv
cvs co -r use_zlib ISpy/Services 
cvs co -r use_zlib ISpy/Analyzers
scram b

3a) Run the test analyzer to make an .ig file from real data:

cmsRun ISpy/Analyzers/python/ispy_XYZ_cfg.py

3b) Use iSpy with your custom configuration file:

You only need to add the iSpy path to your process:

process.load("ISpy/Analyzers/ISpy_Producer_cff")
process.p1 = cms.Path(process.iSpy_sequence)

 

Produce files from shell script

Alternatively, Jinzhong Zhang has created a bash script that can:

• Install the Analyzers
• Produce the ig files from a specified dataset (and run and lumi range)
• Filter on an HLT
• Publish the resulting ig files in a storage element such as CASTOR

The script can be viewed here. One can fetch the script from CVS with the following command:

cvs co -r use_zlib ISpy/Analyzers/ISpy.sh
