Converter: ProMC to LCIO/StdHep files

This converter allows you to convert ProMC archive files from the HepSim Monte Carlo repository with events from Monte Carlo generators to LCIO/StdHep files. To compile this converter, you need Java JDK.

Compilation

source setup.sh
javac promc2lcio.java
javac promc2stdhep.java

Usage:

java promc2lcio   file.promc file.slcio
java promc2stdhep file.promc file.stdhep

Here is a full example:

Get a ProMC file from the HepSim:

wget https://mc.hep.anl.gov/asc/hepsim/events/mumu/250gev/pythia8_higgs_bbar//gev250mumu_higgs_bbar_001.promc

This file contains Monte Carlo events with Higgs decaying to b-jets at e+e- collider at 250 GeV. Now you can explore the events in this file as :

java -jar lib/browser_promc.jar gev250mumu_higgs_bbar_001.promc

Now let's do the conversions:

file="gev250mumu_higgs_bbar_001"
java promc2stdhep ${file}.promc ${file}.stdhep
java promc2lcio   ${file}.promc ${file}.slcio 

The converted files with the extensions stdhep and slcio can be used by the external programs. You can look at the LCIO event 10 as:

javac LCTExpanded.java
java LCTExpanded  ${file}.slcio  10 

Other converters (implemented in C++) can be found in the ProMC package (https://atlaswww.hep.anl.gov/asc/promc/)
