Regading scale and PDF uncertainties
Hi Olivier,
2. Does MG5 supports "MSTW2008LO" PDF set ?
NOTE : I am trying to reproduce some of the results of your paper 1508.00564 (Specifically Table 3 , 4, 5,6,7).
Regards,
Shiba

Hi,
> Is it possible to see the scale and PDF uncertainties in the cross section ? If yes, what switch will do this job in the run_card.dat.
For LO, you have to install syscalc via the "install syscalc" command.
Then you have to set use_syst to T in the run_card (and the associated parameter defining what you call PDF/scale uncertainties.
For any question on SysCalc you can ask Alexis Kalegouropoulos.
> 2. Does MG5 supports "MSTW2008LO" PDF set ?
via the lhapdf interface yes.

For NLO, you do not need external code.
you just have to configure the run_card.cat

Thank you Olivier.
One more question, I saw the result is output already is as the uncertainty.
How does it know if it is a Hessian or MC PDF set?
Is it hardcoded with the id?
thanks

Hi,
You need to have lhapdf install in your path when installing SysCalc.
Cheers,
Olivier

Hi
I think you are just trying to install LHAPDF sets under /usr/local/include where typically users dont have access to - Try to set you custom dir
I am quoting the LHAPDF install page
"
PDF sets (each of which is stored in a unique filesystem directory) should usually be installed in the $prefix/

Hi
No, you have to do something like this
./configure --prefix=
Please read this
https:/
Please note, if you install LHAPDF6x you need also BOOST libraries available in your machine as explained in the above link
Cheers
Alexis
PS (All the above have nothing to do with SysCalc of course ;-)

You will have to set up properly the /bin, /lib like
## Set environment variables
export PATH=$PWD/
export LD_LIBRARY_
export PYTHONPATH=
where "local" is the dir your install the LHAPDF
