Dear rho-experts,
I am trying to optimize my analysis macro, in rel oct14. The basic analysis tool that I use is /rho/.
In
/PndTools/AnalysisTools/PndRhoTupleQA
I see that several blocks are already prepared with useful variables, and actually I make use and I checked some of those. For example:
qa.qaP4("beam", ini, ntp2);
qa.qaComp("Dsm", DslistM[j], ntp2);
qa.qaDalitz("Dsm", DslistM[j], ntp2);
qa.qaVtx("Dsm", DslistM[j], ntp2);
work properly.
I would like to use also the block: qa.qaRecoFull("Dsm", DslistM[j], ntp2);
Is it correct to inizialize it in such a way? Actually the macro runs, but I do not see the variables which I expect to see in my ntuple, once I write this latter line in my macro. Can anybody of you give help? for example, if I wish to see the distribution of de/dX, or if I wish to have the chi2 and probChi2 distributions inside my ntuple structure (I called it 'ntp2'), what shall I do?
Thank you for your useful help,
Elisabetta

Dear Elisabetta,
Please give us a snippet of your code, especially where you do the various calls with the QA tool.
The reason is that you don't want to mix logically independent things within the structure of loops. You don't want to write event based variables (multiplicity, best Chi2...) with candidate based variables (momenta etc.). If you have such differing things, you need separate ntuples for that.
On the other hand, try another prefix for the qaRecoFull() call (e.g. "DsmFull") because it may try to overwrite existing variables.
Cheers
Ralf

Hello Ralf,
here I attach a simplified version of my macro, and the pid.root and simparams.root. It is only for 20 generated events, as a test. Even if I change the name for the block qaRecoFull, the variables are not seen in the tree.
I even tried to comment out all blocks, except the block called "qaRecoFull". No way to get those variables in my ntuple. Then, I suspect that I am still missing something.
If you could kindly have a look, it would be great!
As you see, the histogram of the chi2 is filled. I am trying to get the variables of the block "qaTrk", actually.
Thank you in advance,
Elisabetta
