Hi, at the section 14.20.1 of ROOT documentation it is clearly stated how to do a Draw using a aTString as filtering condition.
Just as follows
root[] MyTree->Draw("Cost:Age","Nation == "FR"")
I have a tree with few branches, and I am interested to filter by subEventTag.

If I do the following
->Draw("hitsAna_energy>>hitsEnergy1_0(100 , 0 , 100)", "subEventTag == "Bi210"");
I get the following output error
ROOT_prompt_11:1:96: error: invalid suffix on literal; C++11 requires a space between literal and identifier [-Wreserved-user-defined-literal]
run0->GetAnalysisTree()->Draw("hitsAna_energy>>hitsEnergy1_0(100 , 0 , 100)", "subEventTag == "Bi210"")
^
ROOT_prompt_11:1:96: error: expected ')'
ROOT_prompt_11:1:30: note: to match this '('
run0->GetAnalysisTree()->Draw("hitsAna_energy>>hitsEnergy1_0(100 , 0 , 100)", "subEventTag == "Bi210"")
^
For me the problem is that the C interpreter believes "subEventTag == " is an argument, and gets puzzled when it sees that it is not followed by comma “,”.
I tried changing double quotes " by single quotes, there is any idea of how this should be properly done?
Thanks!!
