Hello,
I am trying to create a series of filter on my RDataframe, I have a filter as a function of a variable dependent on the maximum value of other variable.
#WP definition 2016
cutlister.define( dft , 'mini' , 'pfRelIso03_all_2' , '(el_neuIso + el_phoIso - (event_rho.rho)*({0}))'.format(Mini_effArea) )
cutlister.define( dft , 'mini' , 'pfRelIso03_all' , '( el_chIso + TMath::Max( 0.0 , pfRelIso03_all_2 ) )/el_pt' )
the member function define() is defined as:
def define(self, df , aod , branch , defs):
df[aod] = df[aod].Define(branch,defs)
pass
While I execute the python script i have met with error:
[shoh@lxplus7110 xAOD]$ ./cutFlow.sh

how do I resolve the ambiguity of calling Max.?
Thanks.
