Hi, Since we installed the new version of root v4/08 (an update from v4/01) h2root doesn't seem to convert my .rz ntuples properly. here is what I do: h2root r222.rz h2root.root 0 Now, on an old converted file (with version 4/01) my program runs fine. I however noticed that the program was failling to properly read the branches on newly converted files. So I deleted the old converted file and replaced it with a new to check it wasn't jsut this file. I have now the same problem with my new converted file: it does the conversion but when I run my program it dosen't seem to be able to read the entries properly anymore. (I have been stupid as I should had renamed my old version as a reference) Here is the code.. he doesn't seem to be able to fullfil my if statement. where I have a cout command.. (which worked on the old converted file before) const long cc=40000; float norm[cc]; int pixid[cc]; int pdid[cc]; int dc; TBranch* b_nch=t->GetBranch("nch"); TBranch* b_norm=t->GetBranch("norm"); TBranch* b_pdid=t->GetBranch("pdid"); TBranch* b_pixid=t->GetBranch("pixid"); b_nch->SetAddress(&dc); b_norm->SetAddress(norm); b_pixid->SetAddress(pixid); b_pdid->SetAddress(pdid); for(int i=0;i<ne;i++){ if (((i+1) % 1000) == 0) cout<<i+1<<endl; t->LoadTree(i); b_nch->GetEntry(i); b_norm->GetEntry(i); b_pixid->GetEntry(i); b_pdid->GetEntry(i); for(int j=0;j<dc;j++) { for(int k=1;k<=64;k++){ if (pixid[j]==k &&pdid[j]==3){ MaPMT3[k-1][i]=norm[j]; cout<<"MaPMT["<<k-1<<"]["<<i<<"]:"<<norm[j]<<endl; } } } } I know it's a bit vague but could it be that there is a conflict with the new version of root ? Or am I being stupid somewhere. I tought I ask you before annoying my sys-admin with a request to go back to the old version of root.
