I need to create a program to convert data files from binary format to a root format.
In this program, the data I’m looking for are:
- a channel number
- a marker (booleen) on this channel
- the energy of the hit coded on this channel
- the time of this hit
So I’ve decided to create a tree with one branch per channel. And in each branch three leaves for the three other parameters (marker, energy and time).
So I have to manipulate a tree with n branches that contains three identical leaves…
If I use the function mytree -> Fill() it will duplicate in each branch the same hit…
So I use mytree->GetBranch(“channel_x”)->Fill() (where x is the number of my channel).
The consequence is at the end of my conversion, if I try to use the TBrowser to visualize my tree its impossible… But if I do it via a routine it works perfectly.
And the use of TChains seems to be impossible…
Did I miss something?
Thank you for your response.
