Good day for everyone! I need help! I have simulated a proton particle track using Geant4dna software. The output file is dna.root - see attach 1. I can visualise this file with a macro “Plot.C”. I can see a file structure using Root Explorer. But i cannot extract data from this file - see attach …

Sorry. Change f to t and get this: In file included from input_line_10:1: /home/local1/dnaphysics-build/d2.cxx:22:2: error: called object type 'void' is not a function or function pointer ((TTreePlayer *)t->GetPlayer())->SetScanFileName(outputname);

sorry I am lost. Can you copy/paste the entire code?

At least one “;” is missing (in the end of the line with “SetScanRedirect”).

[image] rootroot: No no errors, but no output files… The file ‘diump.txt’ is not even created?

Try to download root.dna from here - https://yadi.sk/d/8fN-s6zXz1gyKQ Yes, dump.txt and dump.xml is not created. Nothing…

Note that there is no “ntuple” TTree in your “dna.root” TFile.

Thanks! const char *nname = "dna") Solve the problem!

Alternative use the following script: // Name this file "dump.cxx" and use as: // // root [0] .x dump.cxx("dump.txt") // // Produces "dump.txt" and "dump.xml" files. // void dump(const char *outputname = "dump.txt", const char *fname = "dump.root", const char *nname = "ntuple") { if (!outputname…
