Problem with multi_run

Asked by Nikita

Good Day,

I'm trying to use multi_run command and I've faced with annoying issue.
I've used this command before and I remember this bug, but I can't remember what the solution is.

The problem is when I'm starting multi_run, the following error rises after the Pythia-PGS simulation:

---------------------------------------------------------------------------------------------------------------------------
Command "multi_run 2" interrupted with error:
InvalidCmd : Events file /generation/1/Events/run_01_0/tag_1_pgs_events.lhco does not exits
--------------------------------------------------------------------------------------------------------------------------

The Events folder contains subdirectory names "run_01_0" and this directory contains the following files:
events.lhe.gz
run_01_0_tag_1_banner.txt
run_01_0_tag_2_banner.txt
tag_1_pythia_events.hep.gz
tag_2_pgs.log
tag_2_pgs_events.lhco
tag_2_pgs_events.root
tag_2_pythia.log
tag_2_pythia_events.lhe.gz
tag_2_pythia_lhe_events.root
unweighted_events.lhe.gz
unweighted_events.root

The file tag_1_pgs_events.lhco was replaced with tag_2_pgs_events.lhco.
Why this tag_2 problem rises? How to fix this?

Best Regards,
Nikita

Dear Nikita,

I've tried to reproduce this behavior but everything works fine for me.
Could you check that you are using the lastest version of the code (currently 2.1.2)
and if so could you give me the exact steps that you did, and that I need to do in order to reproduce the problem.

Cheers,

Olivier

PS: I have tried the following list of command:

in MG5:
generate p p > t t~
output TEST_MULTI_PGS

$ cd TEST_MULTI_PGS
$ ./bin/madevent
(and then type the following command)
multi_run 3
multi_run 3
pgs=ON
multi_run 3 run_02
set run_tag tag_2
multi_run 3

as you can see i have try multiple sequence of command to try to reproduce your problem but all of them where working correctly

Dear Oliver,

This is a bit strange, but with the new version I see no problems.
Before the update I've been using v2.0.1.
Thank you!

Nikita
