OSError : [Errno 17] File exists

Hi Liron,

is this a LO or NLO process?

Cheers,

Olivier

Hi Olivier,

It is an NLO process.

Best
Liron

Ok then this is probably linked to your other problem.

Will ask Marco to look at it.

Cheers,

Olivier

Hi Liron,
can you please tell me the exact sequence of commends/run in order to be able to reproduce your error?
Cheers,

Marco

Hi Marco,

If I'm in bin and do ./generate_events but there is already run_01 directory in Events, it doesn't work.
What I do for now is to add "-n run_02".

Thanks
Liron

how do you create the run_01 dir?
i mean, can you tell me the commands to have this error starting from a freshely exported process dir?

Thanks

Marco

Hi,

I enter to the directory:
bin
I then type:
./generate_events -f
If there was no directory run_01 in Events, then it creates it and fill it with all the files:
alllogs_0.html alllogs_1.html alllogs_2.html events.lhe.gz res_0.txt res_1.txt run_34_tag_1_banner.txt RunMaterial.tar.gz summary.txt
If there is already that directory, then I get that error.
Unless I do
./generate_events -f -n run_02
Then I have no problem.

Thanks
Liron

Hi Liron,
I cannot reproduce your error.
To do so i have taken a process (pp> zh [QCD]), and generate events twice
the first time it creates run_01, the second run_02,
and i do not get any error, so this bug looks very strange and not reproducible to me…
you are using 2.1.2, right?

Cheers,

Marco

Hi,

Yes, I have it in one directory, not sure why?!
If you have no idea how/why that thing can happen, I'll just make new directory and copy the Cards.

Best
Liron

just another thing:
have you moved/copied the process directory after output?
Cheers,

Marco

Hi,

No!
but I can tell you then starting new directory with the same process AND the same run_card and param_card works just fine.

Thanks
Liron

and what if in the new dir you execute twice generate_events?

You mean I do generate_events after I have there run_01? Then it makes the run_02 like in other directories.....
Only for that particular directory, it stopped doing it for some reason.

Thanks
Liron

yes that is exactly what i was meaning...
ok, so, even if we do not know why, the problem is kind of solved, right?
Thanks
Marco

Yes, I don't know why for that particular directory it doesn't work anymore.
But for the other directories it works.

Thanks
