Hi,

Could you copy/paste your debug file?

Cheers,

Olivier

Dear Yu,

I'm really confused. the debug file indicates a problem when running the command "check" (without argument)
the check command should indeed have argument.

What I do not understand is that ./bin/generate_events should never use the "check" command.
Are you sure that this is the correct debug file?

Cheers,

Olivier

Yep, I was also confused. I just re-install MG5, then all problems are gone.

Really thanks for your help!

Best,

Yu
