Problem with jets

[Ben Hooberman]

Hello,

I am attempting to analyze the 100 TeV pp samples for the FHC studies that are listed here:

​http://www.snowmass2013.org/tiki-index.php?page=Energy_Frontier_FastSimulation

I have downloaded v3.0.12 of Delphes from the main website (and I'm using ROOT 5.32), while the above site says the samples were produced with v3.0.9.

When I load the Delphes ntuples, I get the error output related to jets below. My guess is that this is due to incompatible Delphes versions, but I'm not sure. I was unable to find v3.0.9 on the Delphes website, to check if that fixes the problem.

Any ideas what causes this and how to fix it? Thanks very much,
Ben

   has the same version (=2) as the active class but a different checksum.
   You should update the version to ClassDef(Jet,3).
   Do not try to write objects with the current class definition,
   the files will not be readable.
