Try to run MG_aMC_v2.3.3 and MG_aMC_v2.6.0 with LHAPDF_v6.2.1

Asked by w-ding on 2018-07-09

I tried to run MG_aMC_v2.3.3 with LHAPDF_v6.2.1, I installed LHAPDF_v6.2.1,I also downloaded the pdf 247000:NNPDF23_lo_as_0130_qed, and modified the file input/mg5_configuration.txt to specify the path lhapdf = /home/wei/CalcHEP/PDF/bin/lhapdf-config, in the run_card :
lhapdf = pdlabel ! PDF set
247000 = lhaid ! if pdlabel=lhapdf, this is the lhapdf number
NNPDF23_lo_as_0130_qed = sys_pdf
in the proc_card.dat:
set lhapdf = /home/wei/CalcHEP/PDF/bin/lhapdf-config
import sm
generate p p > t t~
output -f
launch
And then ran as usual, but it failed:
generate_events run_01
Traceback (most recent call last):

I am sure that I have installed LHAPDF and downloaded the PDF file.

Hi,

You need to have at least 2.6.1 in order to have support of lhapdf 6.2

Cheers,

Olivier

Thank you, Olivier,
Does LHAPDF_6.1.4 work ? I also tried LHAPDF_6.1.4 ,the error was the same.

Hi,

I do not know what the status is for that version, we were suggesting 6.1.6 for a very long period.
(if you do "install lhapdf" this is actually the version that you will install)

Now please try with the latest version of MG5aMC and if you still have problem,
please include the full debug file.

Cheers,

Olivier
