No such file ../MadLoopParams_default.dat

[Joshua Lin]

When running the commands:

generate p p > H [QCD]
output test

and then ./test/bin/generate_events, I get the error:

Command "generate_events " interrupted with error:
IOError : [Errno 2] No such file or directory: '/global/u1/j/jzlin/summer/MG5_aMC_v2_6_2/bin/test/Cards/MadLoopParams_default.dat'

I've attached my debug file as well

Thanks,

I have finally found one OS where to reproduce such error.
I will investigate it more tomorrow.

Cheers,

Olivier

In the meantime,

you can run via
./bin/mg5_aMC
launch XXXXXX

This does not have such issue.

I have pushed the following patch in the development version.

Thanks for the information,
