LHAPDF::MetadataError

Asked by Koay Yong Sheng on 2020-04-13

I recently tried running madgraph with lhapdf in a cluster, and somehow it always end up with some error.
I also tried running systematics within madevent, but it also failed.
I'm not particularly sure whether this is a Madgraph-lhapdf problem or LHAPDF problem or a cluster problem. I apologize if I asked at the wrong place.

Regards,
Koay Yong Sheng

Previous command before running Madgraph were:
>setupATLAS
>lsetup "lcgenv -p LCG_96 x86_64-centos7-gcc8-opt madgraph5amc 2.7.2.atlas3"
>lsetup "lcgenv -p LCG_96 x86_64-centos7-gcc8-opt lhapdf 6.2.3"
>export LHAPDF_DATA_PATH=/cvmfs/sft.cern.ch/lcg/external/lhapdfsets/current/
>/cvmfs/sft.cern.ch/lcg/releases/MCGenerators/madgraph5amc/2.7.2.atlas3-e1369/x86_64-centos7-gcc8-opt/bin/mg5_aMC

Hi,

I would advise to contact lhapdf author about this: <email address hidden>
Do not hesitate to put me in cc in case they things this is related to MG5aMC such that I can directly have the information.

Cheers,

Olivier
