Description
Hello,
Sorry to bug you again so soon, but I have a very simple suggestion.
Background: I am attempting to implement MadGraph -> LHE, then LHE -> Pythia -> Delphes. The easiest way to accomplish this (IMHO) is to run MadGraph independently, then change the Beams:LHEF setting in a Pythia config file, and use one main() to drive both Pythia and Delphes (thanks in large part to your example main).
Issue: So far this has worked great, but today I tried to activate jet matching/merging between MadGraph and Pythia, which required linking in some new Pythia headers. The problem arose because the class Event in "classes/DelphesClasses.h" is ambiguous with Pythia::Event.
My Solution:I decided to rename Event -> TimedEvent, as the base class merely stores some timing information (and an index), changing the 5 lines in "classes/DelphesClasses.h" (including the ClassDef) and ones in "classes/ClassLinkDef.h". I also had to change a few lines in "converters/root2lhco.cpp" (less important) to get the Makefile to fully rebuild.
Thanks for your detector simulator!
Keith
