Also I checked with the TBroswer that there are a range of time values and there are, so not sure why I can only seem to extract all of the same nonsense values. </div> <div><br> </div> <div><br> </div> <div><br> </div> <div>// Take the single tree, containing the position, energy and time</div> <div>TTree* singlesTree = (TTree*)file->Get( "Singles" );</div> <div><br> </div> <div>// Declare variables</div> <div>Float_t globalPosX, energy, time;</div> <div><br> </div> <div>//Source values</div> <div>singlesTree->SetBranchAddress( "globalPosX", &globalPosX );</div> <div>singlesTree->SetBranchAddress( "time", &time );</div> <div>singlesTree->SetBranchAddress( "energy", &energy );<span class="Apple-tab-span" style="white-space:pre"> </span></div> <div><br> </div> <div>//open output file</div> <div>ofstream outputfile;</div> <div>outputfile.open ("ConversionTest.txt");<span class="Apple-tab-span" style="white-space:pre"> </span></div> <div>if (outputfile.is_open()) </div> <div>{<span class="Apple-tab-span" style="white-space:pre"> </span></div> <div><span class="Apple-tab-span" style="white-space:pre"></span></div> <div><span class="Apple-tab-span" style="white-space:pre"></span>for( Int_t ijk = 0; ijk != entriesSingleTree; ++ijk ) //loop over tree</div> <div><span class="Apple-tab-span" style="white-space:pre"></span>{ </div> <div><span class="Apple-tab-span" style="white-space:pre"></span>singlesTree->GetEntry( ijk );</div> <div><span class="Apple-tab-span" style="white-space:pre"></span>outputfile << globalPosX << " " << time << " " << energy << "\n"; //write values to file <span class="Apple-tab-span" style="white-space:pre"></span></div> <div><span class="Apple-tab-span" style="white-space:pre"></span></div> <div><span class="Apple-tab-span" style="white-space:pre"></span>}</div> <div>}</div> <div>outputfile.close();<span class="Apple-tab-span" style="white-space:pre"> </span> </div> <br> <p></p> </div> </body> </html>
