Hi ROOT experts I have a question. I have TTree which has inside a class with vectors. When i save the TTree file, i know that the vectors are size 16x64, and that the data saved from the TTree is correct. However, when I try to retrieve the data from the vectors, I can’t access the different elements.
This is how I create the vectors for the TTree:
Inside class ElectronicsInfo
std::vector< double> rms = std::vector<double>(64,0) ;
std::vector< double> max = std::vector<double>(64,0) ;
std::vector< double> min = std::vector<double>(64,0) ;
std::vector< double> mean = std::vector<double>(64,0) ;
std::vector< double> roinum = std::vector<double>(64,0);
Then I fill with corresponding data, and write to the ROOT file.
Now, I want to analyze the vectors I created:
here is where in run into trouble:
here is my code
XMITInfo* xmitinfo = NULL;
inTree->SetBranchAddress("xmitinfo", &xmitinfo);
for (int ientry=0; ientry<inTree->GetEntries(); ientry++){
inTree->GetEntry(ientry);
for (size_t ifem = 0; ifem < xmitinfo->size(); ifem++){
ElectronicsInfo info = (*xmitinfo)[ifem];
std::vector<double> ROIrms = info.rms;
//when i print the size of my vector it should be 64
std::cout <<ROInum.size() <<std::endl;
}
}
But every time i try to acces ROIrms, everything is always zero.
