Dear experts,
I’m trying to obtain text files and images (pdf, jpeg, whatever) using a PROOF session.
While there are no problems for obtaining a final TTree, I’ m experiencing problem with text files and images. My code (a TSelector) printouts and saves in a text file the number of events and several images. Since PROOF splits the job I have the following issues:
- the printout (I can read it from PROOF log files) corresponds to the fraction of event processed in each worker (which, I suppose is expected)
- the text file is not created
- When trying to save plots I obtain the following error
Error in <TSelectorList::CheckDuplicateName>: an object with the same name: c_CR1e_metnoel_el_jet_dR_min is already in the list
How can I correctly obtain the final text files with all merged numbers (where “merged” in this case means added, not lined) and images?
Another question is on how to save output file in a specific directory. When running PROOF to produce ntuples I would like to save the outputs in a directory different with respect where my running macro is placed.
Thanks for the attention.
Best regards,
Francesco
