The nTuple files are available on CASTOR storage. The can be found in the directory

{{{
/castor/cern.ch/user/d/dmaitre/BlackHatSerpaNtuples/PROCESS/ENERGY/
}}}

where there is a subdirector per part. One can have a list of the parts using (for example)
{{{
#!sh
rfdir /castor/cern.ch/user/d/dmaitre/BlackHatSherpaNtuples/Wm2j/7TeV/
}}}
and one would get 
{{{
born
loop
real
vsub
}}}


The nTuple files can be found on the grid. They are stored on the SE of the Durham node. To access them, one needs access to the logical file catalog (lfc) that the 'pheno' VO uses. To do so do

{{{#!sh
  export LFC_HOST=lfc.grid.sara.nl
}}}

with this one should be able to list the ntuples file for a given process, say Wm1j at 7TeV

{{{#!sh
  lfc-ls /grid/pheno/BHSNtuples/Wm1j/7TeV/
}}}
