The grid files, produced by Alex, are in his public home in afs:
~amott/public/ALPGEN/8TeV/grids/
And in my personal afs area:
~fladias/ALPGEN8TeVGrids
I have to run on the grid files to discover the efficiencies of producing:
The order of the grid files to run is:
For calculating the grid efficiencies, have to run in all the process (through PYTHIA and so on) to get the matching efficiency. I also have to know the cross section, so I can calculate the number of events needed for a given luminosity.
I'm running 1.000.000 .wgt events to get the .unw and matching efficiency

Number of matched events needed: N = sigma . L
Where sigma is the cross section for the given PROCESS, and L is the accumulated luminosity.
So, for 1fb^-1, I have to produce the number of events equal to the cross section given for the process, in fb.
I've runned the test for Alpgen on crab in my CERN afs area. Need to do the same steps in my own personal area in ACCESS from SPRACE.
