Description

Hi,

I was trying to extract some variables and combinations of variables from the Delphes output file to a new ROOT file. The macro I am using is attached. I am using Delphes3 and ROOTv6.14.

The MissingET branch is getting written perfectly because it has constituents for every event. But for the lepton or photon branch, there are some events that are empty. When I am filling up the tree through the event loop, the values of some variables from the previous loop are getting repeated as there's no new value to overwrite it.

Is it possible that I get some ideas, suggestions and/ advice from here? I earlier was discussing in the ROOT forum as it appeared that may be related to ROOT. But that wasn't solved. So, it'll be appreciated if I get some help.

Regards,
Saumyen
