Problem with NLO event production
Dear MadGraph Team,
just for test purposes I tried to generate the following process:
generate u d~ > e+ ve [virt=QCD]
Everything went fine until I wanted to generate the events by the launch command. I work on the lxplus-system of the ATLAS collaboration.
Here is the complete dialog:

load MG5 configuration from input/mg5_
set collier to /afs/cern.
fastjet-config does not seem to correspond to a valid fastjet-config executable (v3+). We will use fjcore instead.
Please set the 'fastjet'variable to the full (absolute) /PATH/TO/
MG5_aMC> set fastjet /PATH/TO/
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
