Dear all,
I am trying to write a TTree whose branches contain arrays and gave a look at
root.cern.ch/root/html/tutorials … ee3.C.html
But I obtain:
Error in TBranch::TBranch: Illegal leaf: X_amp/X_amp[XYSTRIPS]/F
Error in TTree::SetBranchAddress: unknown branch -> X_amp
Could anyone tell me what’s wrong, please?
