Empty Plots for Delphes

[caglar]

Hi there,

I installed Delphes, MadAnalysis, ExRootAnalysis and pythia to my mg5 then i generated events with

generate p p > j j
launch
1 pythia=on
2 pgs=on
3 Delphes=on
0 done
0 done
and after this run ends without any error or something i get empty plots from Delphes

and the Delphes log is something like this

Delphes log

Screenshot of the terminal after i launch

Looks like you are using Delphes 2. This version is not supported any more. Could you try to switch to Delphes 3?

Replying to pavel:

Thx for the quick response. I installed Delphes2 from the mg5 with the

install Delphes2

command and i think there is no Delphes3 in there. Can you tell me how can i install Delphes3 outside of the mg5 program? Sorry for the lack of knowledge i am a fresh starter to linux.

[Pavel Demin]

The command to install Delphes 3 from mg5 is

install Delphes

You can install Delphes 3 outside of the mg5 program by following the instructions from the Quick Tour:

https://cp3.irmp.ucl.ac.be/projects/delphes/wiki/WorkBook/QuickTour

[caglar]

installed Delphes3 and generated new events with same order still empty Delphes plots

[caglar]

terminal, webpage and Dhelphes log

[Pavel Demin]

Is it possible that it's still Delphes 2 is running when you generate new events?

I don't know how mg5 behaves when you have two Delphes versions installed in the same time.

[caglar]

I removed my old Delphes directory simply by "right click and delete" and then installed Delphes3 and then used configure and make commands.

[caglar]

thx for the quick replys i appreciate it.

[Pavel Demin]

I've just noticed the error message about an unknown DETECTOR command on the last screen shot. It means that Cards/delphes_card.dat still points to the Delphes 2 configuration file.

The easiest solution that I know about is to remove the mg5 directory and then reinstall/reconfigure mg5.

I'll do it then thank you for your time.
