Hi @njacazio, looks good, however when I compile the new version, I meet an error: "/Users/zbiao/alice/sw/SOURCES/O2Physics/master/0/DPG/Tasks/qaEfficiency.cxx:1023:21: error: cannot initialize a variable of type 'char *const' with an rvalue of type 'const char *'"

try to swap const char* to char* const or viceversa and in case push the change

Yes, I will have this in another PR, it does not make sense to have it in this one, apologies

Hi @njacazio @mfaggin, It's Ok for me. I think we can go ahead. Thanks a lot!
