Description

Hi,

I'm using MadGraph5 2.2.2 with Delphes install. When I try to launch with Delphes to produce events, the tag_#_delphes_events.root is empty. From the log file:

INFO: initializing module PileUpMerger
ERROR: can't open pile-up file MinBias.pileup
Reading delphes.root
Error in <TChain::LoadTree>: Cannot find tree with name Delphes in file delphes.root
Input file contains 0 events
Exiting...

I asked the MadGraph authors https://answers.launchpad.net/mg5amcnlo/+question/258784 and they didn't know a solution and suggested I ask here. Any suggestions would be appreciated.

Best wishes,
Xanthe Hoad
