MC@NLO with LHAPDF 6.1.4. - no event file, in log file: pdflib could not understand the input

Hi,
I am not an expert of MC@NLO, (without the 'a').
Here is the launchpad page of (MadGraph5_)aMC@NLO.
For support regarding MC@NLO, see here
http://www.hep.phy.cam.ac.uk/theory/webber/MCatNLO/

I have notified one of the MC@NLO developers, Paolo Torrielli about your question.
Best,

Marc

Hello,
could you please try and see if setting LHALINK = DYNAMIC or STATIC
makes some difference?
Cheers,
Paolo

Every pdf set is in the lhapdf/share/LHAPDF directory (lhapdf install automatically installs it here, version 6.1.4 does not have lhapdf -getdata) . For example i have CT10 directory in lhapdf/share/LHAPDF, not in PDFsets directory.

Hi,

when i set LHALINK=STATIC, i get bunch od different mistakes:

My lhapdf directory looks like this:

bin - > lhapdf, lhapdf-config
include -> LHAPDF -> header files..
lib -> libLHAPDF.a libLHAPDF.la libLHAPDF.so pkgconfig python2.7
share -> LHAPDF -> CT10, cteq66 ... pdfsets.index, lhapdf-conf

and i get the error:

i tried to make directory lhapdf/share/LHAPDF/PDFsets and get CT10 directory into PDFsets but i was getting:
Can't find valid PDF CT10/0

i even tried to change LHAPDF to lhapdf but i fot:
can't find pdfsets.index file

Maybe i shoudl download grid files instead of the data files? I installed data files with lhapdf install (it unpacked the data files into the directory CT10 for example)

Or just try with an oder version of lhapdf?

Cheers and thanks.

Ok, i installed lhapdf version 5.9.1 and it works with MC@NLO.

With the newest version of lhapdf (6.1.4) i just couldn't manage it to work.

Hi Milena,
ok, this would have been my next suggestion. I have personally tried
MC@NLO with many versions of LHAPDF5, but never with LHAPDF6, which
has been released after the latest MC@NLO version.
I’ll ask around anyway, to know if someone managed to have it working
with LHAPDF6.
Cheers,
Paolo
