Invalid event format in Delphes when varying qcut
I am running the MadGraph + Pythia8 + Delphes chain, and I am getting a problem similar to this one: https:/
I have installed the latest versions of MadGraph, hepmc, Delphes and ExRootAnalysis. I am running on a Fedora system, with a global root installation (this also happens for a locally installed root v6.12.06).
The strange thing is that this problem happens for specific values of qcut. The process I am looking at is p p > nu nu~ + Jets (up to four), with xqcut = 10 GeV. If I set qcut = 15 GeV, there is no problem, and Delphes runs normally. If I change qcut = 20 GeV or 30 GeV, then I get an "** ERROR: invalid event format" on the Delphes log.
No idea how to proceed. Could I get any help?
