MadGraph5_aMC@NLO

pythia8_path/examples/config.sh is not present

Asked by Siew Yan HOH

Hi,

I am trying to use pythia8.2 to produced parton shower event in .lhe format, I have followed the Pythia8 online manual
http://home.thep.lu.se/~torbjorn/pythia82html/Welcome.html
to interface madgraph to pythia, I have set the pythia8 path relative and also absolute path as it instructed. But when I type "output pythia8" it return error as

Command "output pythia8" interrupted with error:
IndexError : list index out of range
Please report this bug on https://bugs.launchpad.net/madgraph5
More information is found in 'MG5_debug'.
Please attach this file to your report.

I check the MG5_debug, the previous pythia8_path that I specified in the mg5_configuration.txt does not take effect. I followed the comment to locate the config.sh in pythia8/example/config.sh and the config.sh wasn't there ( it does not come with the Pythia8 package, it try to download the package again still not there)

Despite of that, I try another solution which is to specify the pythia8 path interactively:

output pythia8 Pythia8_path

It produced a folder and a makefile as expected in the specified path, while i try to run the make -f Makefile, it return error :
make: *** No rule to make target `../config.mk', needed by `all'. Stop.

I am using old version MG5_aMC_v2_1_0 for some reason, and latest pythia8201. The content of MG5_debug:

is the problem the config.sh is not present or the compatibility of older madgraph5 version ? Is that any other way out? Thanks

Hi,

I’m not sure if this is your problem or not, but at some point Pythia8 change a lot of convention in their way to handle files and this breaks down the function “output pythia8”.
This has been fixed in MG5_aMC 2.2.0. So clearly if you want to have it work with Pythia8.1, you need a more recent version.
I never try with Pythia8.2 but the same should be true.

Tell me if it work after that, if not, I will contact the Pythia author, to see if they change some other stuff.

Cheers,

Olivier

Hi,

I tried with latest version MG5_aMC 2.2.1, to pythia8.1, despite I have specified the pythia8 path in the mg5_configuration, this is what i got

Madgraph cannot output into the Pythia8, but put the folder in madgraph bin folder.

Hi,

Could you try the following patch:

                     else:

This should solve the problem ( I guess).

Thanks,
