LHCO conversion fault

[fan]

Hi,

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 v3.0.9 of Delphes from
​​https://github.com/zhenbinwu/CMSUpgrade/tree/master/Delphes-3.0.9
and I'm using ROOT 5.34,but conversion this file to LHCO file using root2lhco encountered following error:
Reading /home/dingran/example_root2lhco/B-4p-0-1-v1510_14TEV_NoPileUp_9762392.root

It seems the root file do not contain the 'Track' and 'Tower' branches,I appreciate that if you have any suggestion.
PS:my root file is:B-4p-0-1-v1510_14TEV_NoPileUp_9762392.root

thanks
