Invalid Particle format Error and Warnings

[Aimane]

Hello,

I am having some issues when running Delphes. I am doing simulations of several processes (background + signal) using Whizard, Pythia and Delphes. I need quite large samples (500000 or 1000000 events). I have already done it a first time using ILD card in Delphes when interfacing with Pythia. Then, I needed to edit the ILD card (jet clustering parameters, muon isolation parameters) and that's when Delphes started crashing after "ERROR : Invalid Particle Format". I couldn't get one-million-event samples with my new cards ILDc and ILDd. I had to generate 500000 events only and it's not working for all processes when using ILDd.
could it be a problem with the cards ? The statistics ? or Pythia output?
I attached the two cards I am using and the Pythia card. I generate these processes : ee->HZ ; ee->Z; ee->ZZ; ee-> ZGamma; ee->bbbar ; ee->mumu ; ee->WW ;

I also get lots of warnings of the type in most of the cases :
Warning in <TVector3::PseudoRapidity>: transvers momentum = 0! return +/- 10e10
I don't know what causes them and if they have an impact on Delphes output.

Hi,

the "ERROR : Invalid Particle Format" looks more like a Pythia8 error than Delphes one...
You can try to raise the number of allowed errors in Pythia8 card.

Main:timesAllowErrors = 100

Hi Michele,

So, I suppose I need to add : pythia.readString("Main:timesAllowErrors = 100") right ?
Thank you very much for your help
