Hi Heather,
> Is it possible to call TMath::Min from within a TCut
No it is not. The formula used by TTree::Draw and the same as
the TFormula. It is only a limited subset of C++ which is
described at http://root.cern.ch/root/html/TFormula.html#TFormula:Analyze.
Cheers,
Philippe.

Subject: [ROOT] MakeClass and TEventList
Hi,
I am using ROOT 3.00.06 on Windows.
2 questions:
In the code generated by TTree::MakeClass, would it be possible to include
code that would use a TEventList if the TTree is setup to use a TEventList?
It is certainly possible to modify the code to use the eventlist - but it
would be nice if it were done automatically...or am I using the MakeClass
code incorrectly?
Second question:
Is it possible to call TMath::Min from within a TCut passed to a
TTree:Draw? It does not seem to work for me:
t->Draw("Event_Id", "TMath::Min(entry1, entry2) < 5");
I've tried Min as well..
Thanks,
Heather
