MadGraph crashes with LHAPDF 6.2.1

[Ricardo Barrué]

When I try to generate data using Madgraph version 2.6.0 using LHAPDF 6.2.1 it throws a weird error (probably related to the MG-LHAPDF interface):

"Error detected in "generate_events "
write debug file /mnt/Data/Higgs-CP/tests/crossx_calcs/sm_nocuts_14tev_w_l_50k/run_01_tag_1_debug.log

Hi,

lhapdf 6.2.1 is not compatible with MG5aMC 2.6.0, you need at least MG5aMC version 2.6.1 for that.

Cheers,

Olivier
