Hello
I am new to ROOT and working on extracting Jet information from leaf with TRefArray formation. Following is a specific leaf information when I do Print()
`*............................................................................*
*Br 240 :Jet.Constituents : TRefArray Constituents[Jet_] *
*Entries : 10000 : Total Size= 2008930 bytes File Size = 788086 *
*Baskets : 23 : Basket Size= 184320 bytes Compression= 2.55 *
*............................................................................*`
I did find some macro that can extract around line 174
https://github.com/delphes/delphes/blob/master/examples/Example3.C#l196
This shows a way to extract information from TRefArray but I would like to know if there is a way to convert into PyROOT or to use PyROOT command that can do the same
Also, how can I read a leaf as an array?
This is what I tried so far in python
import ROOT
f = ROOT.TFile("wj_delphes_events.root", "read")
myTree = f.Get("Delphes")
entry = myTree.GetEntry()
for entr in myTree:
print(entr.Jet)
break
but result was
<ROOT.TClonesArray object ("Jets") at 0x7f85d86d4420>
