printing many runs results to one file

Asked by John Doe

Hi MG5 developers. I would like to ask a question on the usage of the command print_results. I've just run the example
MG5 script in FAQ 2186. As I expected from my own experience, the command print_results at the end of the script
prints only the result of the last run:
> $ cat cross_section_top.txt
> === Results Summary for run: run_03 tag: tag_1 process: example ===
> Cross-section : 274.1 +- 0.8424 pb
> Nb of events : 10000
I would like to know how to have the results of the three runs in that example collected in one text file.

Thanks in advance for your help.

Hi john,

By running the examples (just running tt~ and not tt~j to gain time). I get:

# run_name tag cross error Nb_event cross_after_matching nb_event_after matching
run_01 tag_1 547.667 0.494672675716 10000
run_02 tag_1 478.096 0.630660540545 10000
run_03 tag_1 419.387 0.539553851433 10000

This is with version 2.3

Cheers,

Olivier

HI Olivier, thanks for your prompt reply. I was using 2.2.3, but after switching to 2.3.0
it works just as you say. (By the way, congrats for the new version with loop-induced
processes. gg>h takes about a couple of minutes in my box. Quite impressive.)
