[mcstas-users] Using Virtual_output Component

Dear McStas experts,

I have optimized my chopper and guide system, and now I am trying to use 
the |Virtual_output| Component. However I can only use a neutron count 
of 100000000 to perform my simulation in this way, if I try to send more 
I get the message : Job exited abnormally.

Doe it happen because the file I am trying to create is just huge?

Then, what is the best way to use such a component?

At the moment I have it as:

COMPONENT fichier_sortie = Virtual_output(
    file = "exit_guide_result.dat", type = "double")

Also how can I be sure I get the right intensity distribution? By the 
way I am using the SNS_source.component as input, and I would like to 
preserve the ToF-lambda distribution, once using the file = 
"exit_guide_result.dat" as input file for the |Virtual_input| Component.

Many thanks
