Hi, here is what I am trying to do. I have a root histogram in a .root file with experimental data that I want to sample for my simulation with the TH1F GetRandom() method.
Now this seems not to be trivial.
I have both an aida connection to root and a direct connection.
The direct connection works seemingly fine, I can open the root file get a pointer to the histo and all. But all GetRandom() gives me is not a number "nan". Also GetBinCenter(some integer) gives the same result.
On the other hand, in AIDA I don't know how to import the histogram and sample it. I have not found documentation for anything else than writing output to histograms.
Is there perhaps some example of this somewhere? I can by no means be the first person doing this. Any help is greatly appreciated.
