Yes, I've tried but it doesn't really help since I got an error in next step:

no = 0 | name = C14R2_vert_b2_z0_1.root | path = "rfio://castor/cern.ch/user/a/apriebe/C14R2_vert_b2_z0_1.root" nazwa_pomocnicza = "rfio://castor/cern.ch/user/a/apriebe/C14R2_vert_b2_z0_1.root" Error in <TFile::TFile>: file cern.ch/user/a/apriebe/C14R2_vert_b2_z0_1.root" does not exist

Hi,

Did you try rfio://castor/cern.ch/user/a/apriebe/C14R2_vert_b2_z0_1.root

I'm having a script with a list of files stored on castor (1st element - number, 2nd - name of file, 3rd - complete path to castor file). What I want to do is to go through all lines of text file and derive data from all .root files. Unfortunately I obtain an error:

root [0]
Processing ana.C...

Could you please advise me what I shall change?

Here is part of my code:

//open file and read it

     ifstream into;
     into.open("../../../../roocik/C14R2_vert_b2_z0.C");

     string line;
     char* cline;
     char name[200], path[200];
     Int_t no, no_last;

     while(into) {
      getline(into,line);
      cline=line.c_str();
      sscanf(cline,"%d %s %s",&no,name,path);
      cout << "no = "<<no<<" | name = "<<name<<" | path = "<<path<<endl;

      TString nazwa_pomocnicza(path);
      cout << "nazwa_pomocnicza = "<<nazwa_pomocnicza<<endl;



//      chws.Add(path);

//      chws.Add(nazwa_pomocnicza.Data());

      TFile *chws = TFile::Open(nazwa_pomocnicza);
      cout << "File open" << endl;
      // types of events
       Event* evQ = new Event();  // event in Q5
         TTree *ttree = (TTree*)chws->Get("tree");

//chws.Add("rfio:/castor/cern.ch/user/a/apriebe/C14R2_vert_b2_z0_2.root");

       Particle* evP = new Particle();  // event in Q5
         ttree->SetBranchAddress("Event", &evQ);


//           chws.SetBranchAddress("MQI.",&evQ);

          cout << " SetBranchAddress " << endl;
            cout << " Problem za chwile" << endl;
        TBranch *brQ = chws->GetBranch("MQI.");
