running a bash code

Olivier Mattelaer suggests this article as an answer to your question:
FAQ #2186: “How to script MG5 run?”.

Note that if you just want to keep all the cards as in a previous run then you can also do
./bin/generate_events -f

Cheers,

Olivier

Hi Olivier,

If I understand right, you mean:

1) cd MG directory/ work_area and here build the .sh script
2)in the .sh script should stay first ./../bin/mg5_aMC and write exactly the list of commands to run;
3) and at the end pf the .sh scrit should be ./bin/madevent
 so more or less something like this?

#!/bin/bash

cd /afs/cern.ch/work/m/mmelodea/private/CMSSW_8_0_2/src/MG5_aMC_v2_6_1/work_area/

eval `scramv1 runtime -sh`

./../bin/mg5_aMC

import model BSM_gg_hh
generate p p > h h
output RECAS_stuff
launch RECAS_stuff
shower=Pythia6
detector=PGS
analysis=ExRoot
madspin=OFF
reweight=OFF

cd /afs/cern.ch/work/m/mmelodea/private/CMSSW_8_0_2/src/MG5_aMC_v2_6_1/work_area/PP_HH_bbZZ_bb4l/Events/

eval `scramv2 runtime -sh`

./../bin/madevent > madgraph_1.log

Because I am not getting it really.
What should I do better?

Hi,

No you should do:
echo "import model BSM_gg_hh" > mycmd
echo "generate p p > h h" >> mycmd
#(I let you continue all those line like that)
./../bin/mg5_aMC mycmd > madgraph_1.log

Cheers,

Olivier

Hi Olivier,
I tried as you told me over there doing:

#!/bin/bash

echo "import model BSM_gg_hh" >mycmd

echo "generate p p > h h" >mycmd

echo "output RECAS_stuff" >mycmd

echo "launch RECAS_stuff" >mycmd

echo "shower=Pythia6 " >mycmd

echo "detector=PGS" >mycmd

echo "analysis=ExRoot" >mycmd

cd /MG5_aMC_v2_6_1/work_area/

eval `scramv1 runtime -sh`

./../bin/mg5_aMC mycmd > py_pgs_del.log

but as error I get:

load MG5 configuration from ../input/mg5_configuration.txt
None does not seem to correspond to a valid fastjet-config executable (v3+). We will use fjcore instead.
 Please set the 'fastjet'variable to the full (absolute) /PATH/TO/fastjet-config (including fastjet-config).

The import format was not given, so we guess it as command
analysis=ExRoot
^[[1;34mCommand "analysis=ExRoot" not recognized, please try again^[[0m
quit

what should I do?

Cheers
I.M.

and when I do only

./../bin/mg5_aMC > py_pgs_del.log

so without mycmd here, I do get from py_pgs_del.log:

and nothing else.

It seams that my mash system here doesn't read those commands in that way written over here.
What do you suggest me ?

Cheers
I.M.

Hi Olivier,

yes indeed now the mycmd file has those lines, but the script doesnt make the work:

#!/bin/bash

echo "import model BSM_gg_hh">> mycmd

echo "generate p p > h h">> mycmd

echo "output RECAS_stuff">> mycmd

echo "launch RECAS_stuff">> mycmd

echo "shower=Pythia6">> mycmd

echo "detector=PGS">> mycmd

echo "analysis=ExRoot">> mycmd

echo "madspin=OFF">> mycmd

echo "reweight=OFF">> mycmd

cd /lustrehome/imargjek/CMSSW_8_0_2/src/MG5_aMC_v2_6_1/work_area/

eval `scramv1 runtime -sh`

./..bin/mg5_aMC mycmd > py_pgs_del.log

but the py_pgs_del.log is totally empty. the job doesn't start.

Anyway, Olivier: I have found the mistake now and it is working!

I used wrong thhose commands where they should be in different place to let the .sh file work, more:

#!/bin/bash

cd /MG5_aMC_v2_6_1/work_area/

echo "import model BSM_gg_hh"> mycmd

echo "generate p p > h h">> mycmd

echo "output RECAS_stuff">> mycmd

echo "launch RECAS_stuff">> mycmd

echo "shower=Pythia6">> mycmd

echo "detector=PGS">> mycmd

echo "analysis=ExRoot">> mycmd

echo "madspin=OFF">> mycmd

echo "reweight=OFF">> mycmd

eval `scramv1 runtime -sh`

./../bin/mg5_aMC mycmd > py_pgs_del.log 2>&1

now it working perfectly!!

Thank you Olivier!

Thanks Olivier Mattelaer, that solved my question.

Olivier, one more question:

So, in the .sh file to change for example in the par_card.dat from the .sh script how should I do that?

Just like this:

echo "set mt=120" >>mycmd?

or how?

Cheers
I.M.

yes

Thank you Olivier! you are the best!

How can I send 2 and more jobbs at the same time using the same:

echo "import model BSM_gg_hh" >mycmd
echo "generate p p > h h" >mycmd

but for different outputs with respective different conditions from the par_car.dat?

Cheers
I.M.

Not sure what you want here and they are probably plenty of ways of doing it.

For example, can do something like (in your mycmd file)
generate p p > t t~
output DIR1
generate p p > h h [QCD]
output DIR2
launch DIR1
set mt 150
launch DIR2
set mt180

You can also do the same via two mycmd file (which is probably better for the above example)

Cheers,

Olivier
