MC@NLO crashing when testing HiggsAnalysis

Asked by Angel

Hi,

I am using MC@NLO version 4.10 and I am trying to compile and run the HWppAnalyzer/HiggsAnalysis.cc example. However I am getting:

 gcc -I/home/acampoverde/Programs/MC@NLO/include -c /home/acampoverde/Programs/MC@NLO/srcCommon/trapfpe.c
gfortran -w -O2 -fno-automatic mcatnlo_qqmain_pp.o mcatnlo_qqxsec.o mcatnlo_helas2.o mcatnlo_date.o mcatnlo_int.o mcatnlo_uxdate.o mcatnlo_uti.o mcatnlo_str.o linux.o mcatnlo_stdlhe.o mcatnlo_pdftomlm.o mcatnlo_libofpdf.o dummies.o trapfpe.o -o QQNLO_EXE_THISLIB
At line 514 of file /home/acampoverde/Programs/MC@NLO/srcHerwigpp/mcatnlo_qqmain_pp.f (unit = 5, file = 'stdin')
Fortran runtime error: Bad integer for item 2 in list input
rm: cannot remove ‘ttb_a.events’: No such file or directory
rm: cannot remove ‘ttb_b.events’: No such file or directory
runNLO did not succeed, exit status=1

I am also using ThePEG 1.9.2, LHAPDF 6.1.5 and Herwig++-2.7.1. I think I cannot attach the MCatNLO.inputs file here, (can you confirm that?), so I put it in http://pastebin.com/K3DjZKbF is there anything I am doing wrong in that file?

Thanks.

Dear Angel,

thanks for your feedback, even if this is not the place where
to talk about the old MC@NLO. I'll try to answer, but if this
does not solve, please write an email to the MC@NLO authors
(<email address hidden>, <email address hidden>,
<email address hidden>, <email address hidden>,
<email address hidden>). Moreover, MC@NLO has been
completely superseded by MadGraph5_aMC@NLO, which I
warmly recommend to use.

The problem seems to be at an earlier stage with respect to
the analysis, i.e. the code does not even start integrating the
cross section. There are two suspect things in your error message.
First, the executable name ends with 'THISLIB', which means
that you are using the internal MC@NLO PDF library. Is this
intended? Did you download, install, and link this library?
Second, I don't think MC@NLO supports LHAPDF6, hence I
would suggest to switch to LHAPDF5 in case the PDF set you
need is supported there.

You can refer to the webpage
http://www.hep.phy.cam.ac.uk/theory/webber/MCatNLO/
and to the manuals therein for information about the correct
compilation of MC@NLO with the various PDF libraries.

Cheers.
Paolo

Hi,

Thanks for your answer. I did not know I was using an old version of MC@NLO, thanks for informing me. I will close this and try the new version.
