mkPostProc now creates the folder MCl1loose2018v9__MCCorr2018v9NoJERInHorn__l2tightOR2018v9__RDF_JES[up/do]_suffix in /eos/cms/store/group/phys_higgs/cmshww/amassiro/HWWNano/Summer20UL18_106x_nAODv9_Full2018v9/ and stores in that folder the JES up and JES do systematics.
It can be easily extended to '17 and '16 copying the JES_18 step
