What kind of complain? This should have worked with or without a cut.

It would be better to use:
rtree->SetBranchAddress("info",&info);
Cheers,

Subject: [ROOT] tree and streams
Hi Rooters,
I have a problem with my stream definitions in trees. Below you can see
a part from my code.
while(!input_file.eof()){
char run_no[20];
int tower_no;
input_file >> run_no >> tower_no;
if (input_file.fail()) { break; }
int elmfiber = tower_no - 1;
int hadfiber = tower_no + 12;
char s[256];
char tower[256];
strstream sstream(s, 256, ios::in | ios::out);
sstream << "/reco/data/TB2003_JUL/" << run_no << ends;
strstream sstream(tower,256,ios::in |ios::out);
sstream << "towers[" << elmfiber << "].e+towers[" <<
hadfiber<< "].e" << ends;
TFile f(s);
TTree *rtree = (TTree *)f.Get("Run");
RecoInfo *info = new RecoInfo();
RecoRun *run = new RecoRun();
RecoEvent *event = new RecoEvent();
RecoTrigger *trigger = new RecoTrigger();
RecoPhase *phase = new RecoPhase();
RecoHCAL *hcal = new RecoHCAL();
RecoCluster *cluster = new RecoCluster();
rtree->GetBranch("info")->SetAddress(&info);
rtree->GetBranch("run")->SetAddress(&run);
TTree *etree = (TTree *)f.Get("Event");
etree->GetBranch("event")->SetAddress(&event);
etree->GetBranch("trigger")->SetAddress(&trigger);
etree->GetBranch("phase")->SetAddress(&phase);
etree->GetBranch("hcal")->SetAddress(&hcal);
TCanvas *c1 = new TCanvas("c1","c1",20,10,900,600);
c1->Divide(2,1);
c1->cd(1);
etree->Draw("c3x3.e","c3x3.e<5000");
<---------------This works without any problem.
c1->cd(2);
etree->Draw(tower); <--------------------This also works,
but when I want to put a cut like before root is complaining.
How can I use Draw() method with all options for this tower stream.
