Hi @fgrosa ! Thanks for the PR. For me, it is fine to remove this generator since it's quite old and I don't think it is used anymore. However, I would suggest removing the .ini file which points to it (https://github.com/AliceO2Group/O2DPG/blob/master/MC/config/PWGHF/ini/GeneratorHF.ini) and the .sh example for embedded simulations (https://github.com/AliceO2Group/O2DPG/blob/master/MC/run/PWGHF/run_embedding.sh) that points to the .ini file, as well.

Good point @stefanopolitano! I removed another bunch of obsolete files on top of what you suggested.

Hi @lucamicheletti93 @ffionda @crisjahnke we noticed that the generator https://github.com/AliceO2Group/O2DPG/blob/master/MC/config/PWGHF/external/generator/GeneratorHF.C that I am removing is used in DQ (https://github.com/AliceO2Group/O2DPG/blob/master/MC/config/PWGDQ/external/generator/GeneratorCharmToMu_EvtGen.C). Please note that this is obsolete, and, in case you need a generator for Pb-Pb from HF you should use this one https://github.com/AliceO2Group/O2DPG/blob/master/MC/config/PWGHF/external/generator/generator_pythia8_embed_hf.C. We will anyway don't merge this PR until you confirm us that it's good for you!

@fgrosa thanks a lot! I checked with @ffionda and we confirm that it is fine for us. We are not really using it, and in case we will upgrade to the new one.

Hi @lucamicheletti93 ! Thanks for the update, I don't have any further comment. Approved!
