Hello everyone,

I am using the root class TFractionFitter and would like to hand over the weights of my MC histograms to the fitter with


but no matter what I try, I obtain a segmentation fault. Documentation tells me the second argument should be a TH1* pointer.
Does any one have experience with this?

Thanks in advance,

Is your argument histogram a TH1* ?


I have tried TH1F* and TH1D*. Neither works but this post shows that it should be the right type… … a9b0854507
