Process in Madgraph

Asked by Matt on 2017-09-20

Hello,

it's the first time I use Madgraph on HEPMDB.
I want to generate 10k events for a process of that kind:
 p p > e+ e+ j j,
using a UFO model previously uploaded.
Could you please suggest me how to proceed in HEPMDB?

Thank you in advance,

Matt.

Hello Matt,
you need to use

"Calculate" session
and use Madgraph menu to
1. run process card
2. generate events

Cheers,
Sasha

Dear Sasha,

Thank you for your reply, now things seem to work in a different way, however I’m still not sure on how to proceed.
I’m trying to proceed in the following way:

“Calculate” session -> Madgraph menu
- “Import model”: MY_MODEL-UFO
- Edit proc_card_mg5.dat, for example writing
   import model MY_MODEL-UFO
   define p = g u c d s u~ c~ d~ s~
   define j = g u c d s u~ c~ d~ s~
   generate p p > e+ e+ j j
   output
- “Save"
- “Run process card”

However it seems that something goes wrong since this message comes out:

You successfully submitted a job on HPCx : #bash: line 0: cd: /home/hepmdb/users/1798/madgraph/PROCESS: No such file or directory
qsub: script file 'qsub_madgraph.dat' cannot be loaded - No such file or directory.

I hope I was clear enough.

Thank you in advance.
Best,

Matt.

Dear Matt,
could you reset your account,
and try again?
I have made changes and installed new version of MG which requires users to
reset the account, see menu in the upper right corner of the calculate
section.

Also, please make sure that you
have
output PROCESS
statement in your process card
at the end -- the default folder name we decided to go with
at HEPMDB

IF you still will have problem,
please let me know.

Cheers
Sasha

P.S.

output PROCESS
appears in a template
of every proc card, just do not erase it.

Dear Matt,

Looks like you had a successful run.

Please confirm.

Cheers,

Sasha

Dear Sasha,

sorry to open again this ticket, but it seems that I still have some problems with the Madgraph interface, more precisely I can't see any output file.

Thank you again.

Cheers,
Matt.

Dan Locke (danl0) said : #10

Hi Matt,

I can see that this has been caused when we updated to the latest MadGraph version. I will look into this and get back to you.

Thanks,
Dan

Dan Locke (danl0) said : #11

Hi Matt,

I have fixed this issue and run some tests and everything appears to be working fine for me. Please note that you may have to do "Menu->Reset account" in order for the changes to work for you. Also please check that your model file is in the correct format, all model files should be zipped as a .tar.gz. If you have any further issues then please let us know!

Regards
Dan

Matt (elvin.j) said : #12

Hi Dan.

thanks for the answer. I am sorry to say that I still have problems: I tried as before by importing my model (that I think was compressed as .tar.gz as you specified) and then by editing the "proc_card_mg5.dat" just substituting the name of the model with mine, and the process that I want to generate. After running this card with the command "Run proc card", and obviously waiting for the job to be finished, I have tried with "Run event simulation".
Now I see my run in the events folder, but it seems that the two files inside are is all empty, or rather it seems impossible to open and/or download them.

Probably is just about my procedure, so please let me know if I am committing any mistakes.

Thank you in advance.
Cheers,
Matt.

Dan Locke (danl0) said : #13

Hi Matt,

I can see the issue, I will work on a fix and get back to you..

Regards
Dan

Dan Locke (danl0) said : #14

Please reset account and rerun, it should work finally.

Matt (elvin.j) said : #15

Hi,

thanks for your effert. Now the cross section is correctly calculated, however, it is still not possible to download the LHE files, although I have tried with "Copy file to "LHE files and plots"" the files cannot be opened or seen in the folder "LHE flies and plots".

Cheers,
Matt

Best Dan Locke (danl0) said : #16

Hi Matt,

You must double click on one of the directories listed in "Madgraph Events Folder" menu, and then select the relevant .lhe.gz to copy to"LHE files and plots". Then go Madgraph->View LHE and NT folder, then you may either download the events file or use File->Uncompress before plotting if you wish.

I appreciate this isn't as clear as it should be, I will improve this!

Regards
Dan
