problem in showering
Hello,
I am producing p p > t t~ [QCD]
I am trying to use NLO and shower with Pythia. But getting some error message when the showering starts. I don't know what's going wrong from my side. Please suggest something on this matter.
This is the output I am getting -

I have placed the log file in my public: /afs/cern.

I guess there is a problem in selecting the "ANALYSE" in the shower_card. Can you please also elaborate on how can I select that file?

Also one of my objectives is to observe the negative weighted events. Please let me know how I can see that part as well.
Thanks,
