By using CNVnator, I managed to create the .root file but from there I can’t go any further because when I try to create the histograms, it seem to be working, but it never creates any files after it’s done.
New information is added to the .root file you provided in the command line.
During next calculation step CNVnator will extract this information from the file.
To browse the content of the .root file you can start ROOT and open browser (type “new TBrowser”).
Please see http://root.cern.ch for details.
