Hello!

Finally I made it and now i can get the nfile.root. but now I am copying a next problem. I am opening ROOT and I try to see the plot. The output of my terminal is the following.

root [9] TFile f("~/Desktop/kulchi.root");     
root [10] f.ls();
TFile**		/home/user/Desktop/kulchi.root	
 TFile*		/home/user/Desktop/kulchi.root	
  KEY: TH1D	12;1	(transmit, charged) : space angle: dN/dOmega (deg)
  KEY: TH1D	13;1	(transmit, charged) : projected angle at exit (deg)
root [11] 12.Draw ();
