error with "shower=pythia8"

Hi,

My guess is that you are trying to run with piping via the stdin.
When piping, the syntax is much more rigid and you are force to write explicitly when you pass from one question to the next.

A more robust way (in the context of retro-compability with future version) is to use your script but pass the path to your file as argument instead of piping it:
I.e. Do not do
./bin/mg5_aMC < PATH
But do
./bin/mg5_aMC PATH

With the second syntax, the syntax of your file is much more flexible and it runs as needed.

Cheers,

Olivier

PS: this would be the same without pythia8 actually.

Hi Olivier,

Thanks for explanation! But the comand I'm using is the one you suggested. So what should I do? Thanks!

Hi,

This is really surprising. I have tested your file with both syntax, and I reproduce your error message when using the wrong syntax.
So are you really sure that you are using the correct syntax?

Otherwise, I would need you to tell me exactly what you do.
Such that I can try to reproduce your bug even with the correct syntax.
It might be useful that you send me your exact command file by mail to check if this is not a formatting issue (like \r\n for the end of the line)

Cheers,

Olivier

Hi Olivier,

Here attached is my script. The command I'm using is:
    ./bin/mg5_aMC script_contur_SM.txt
Maybe some issue I didn't realize, please point to me, if you find it.
Thanks a lot!

Cheers,
Sijing

Hi,

Please either send me the file on my email or convert first the question to a bug (attachment are not allowed for questions).

Hi,

I actually do not reproduce your error when doing
>> ./bin/mg5_aMC script_contur_SM.txt

So my only suggestions would be to change your script to: (i.e. explicitly write when you finish a question to avoid problem with the automatic detection of the end of such question)

Cheers,

Olivier
