Hi,

Thanks for the information

Did you use 2.5.4?
This should be fixed in that version.

Cheers,

Olivier

Thanks Olivier.

I was using the version 2.5.3. But, as you have said the bug is gone with the version 2.5.4. However, I am facing a new bug given as follows:

Command "generate_events run_01" interrupted with error:
InvalidCmd : Could not find cross-section and event number information in Pythia8 log

I am facing this bug when I am generating the SUSY process p p > b1 b1~, (b1 > b n1), (b1~ > b~ n1)

Cheers!

[Olivier Mattelaer (olivier-mattelaer)]

Weird, that is working nicely for me.

Maybe Valentin might help you on that.

Cheers,

Olivier

PS: Maybe it can be usefull if you can attach your pythia8 card.

[Valentin Hirschi (valentin-hirschi)]

Well, the problem comes from the fact that in your case, the Pythia8 log file resulting from the showering of your events did not contain the basic information that I expect to always be there.

In more technical terms, the parsing of this log files done in the function 'parse_PY8_log_file(' in madgraph/interface/madevent_interface.py failed and I decided to interrupt the run when this happens (because I think it should never happen if the showering went fine).

So please, attach here the Pythia8 log file that you should be able to find in your directory:

<PROC_OUTPUT>/Events/run_XXX/tag_YYY_Pythia8.log

(Please adapt XXX, YYY and the name of the exact of the pythia8 log (which I don't remember by heart) to your case).
