Wrong LHAPDF set number
Hello,
I'm trying to generate events using the built-in top effective theory model, using the following commands:
>import model TopEffTh
>generate p p > t t~ NP=2 , ( t > b W+ NP=0 , W+ > vl l+ NP=0 ) , ( t~ > b~ W- NP=0 , W- > vl~ l- NP=0 )
>output tt_14Tev_
>launch -i tt_14Tev_
>multi_run 10 L15_OtG1_0
Using built-in pythia for hadronisation. I'm using the latest version of MG. The cards used for the generation are included (I didn't touch the Pythia card).
During generation, everything works fine until Pythia is launched: it doesn't output any data, and in tag_1_pythia.log (included) I find the line:
WRONG LHAPDF set number = 200400 given! STOP EXE!
It then goes on to the next run.
I never encountered this problem before when generating events. Could it be because of this particular model?

I thought I could include files...
Here's the Pythia card:
!...Parton showering on or off
MSTP(61)=1
MSTP(71)=1
!...Fragmentati
MSTJ(1)=1
!...Multiple interactions on or off
MSTP(81)=20
!...Don't stop execution after 10 errors
MSTU(21)=1
!...PDFset if MG set not supported by pythia-pgs package (set in lhapdf5 or higher)

Problem solved thanks to Pierre: LHAPDF was simply not installed (though MG wanted to use it by default: weird!?!). Workaround: changing 'nn23lo1' to 'cteq6l1' in the run_card.dat.

Is it possible that you didn't use the latest version of pythia-pgs?

Hi Olivier,
The Pythia version used is 6.426. As I said, I didn't change anything regarding Pythia: everything is "out-of-the-box", with the latest version of MG5_AMC installed.
When MG is updated using bazaar, it also updates the external packages such as pythia and delphes, doesn't it?

Hi Sebastien,
No external packages are not modified automatically.
So this should be the reason of your problem.

I tried installing another instance of MG, which should also give me the latest version of the external packages, but when starting MG (even after installing pythia-pgs) I get the message:
lhapdf-config does not seem to correspond to a valid lhapdf-config executable.
Please set the 'lhapdf' variable to the (absolute) /PATH/TO/
Note that you can still compile and run aMC@NLO with the built-in PDFs
MG5_aMC> set lhapdf /PATH/TO/
Does it mean I have to install lhapdf manually? It is not shown as external package when typing "help install".
Cheers,
Sébastien

Actually, this is not mandatory to have the code linked to lhapdf.
