HepMC filter

HepMC filter

HepMC filter is a simple application that reads a file in HepMC format and selects only those events that pass certain cuts. The idea is to reduce a number of events we need to process after the selection.

Getting and Compiling the HepMC filter

* On tau1.hep.utexas.edu:

NOTE: To download the source file you need to have an access to ATLAS Subversion system.

1. Set up SVNROOT system variable that points to the ATLAS user's repository

export SVNROOT=svn+ssh://<username>@svn.cern.ch/reps/atlasusr

where <username> is your username on ATLAS.

2. Check-out the package from SVN

svn co $SVNROOT/yuraic/ttH/Projects/HepMC_Filter/trunk HepMC_Filter

This will create HepMC_Filter directory and check-out a package in it. If you want to check-out a version with certain tag, use the following command

svn co $SVNROOT/yuraic/ttH/Projects/HepMC_Filter/tags/HepMC_Filter-00-00-03 HepMC_Filter

This will check-out version HepMC_Filter-00-00-03 of the HepMC filter.
3. Source the setup.file

cd HepMC_Filter
source setup.sh

4. Compile the filter

gmake
gmake clean

At this stage you must have 'HepMC_Filter.exe' in
