TH1 Komogorov test with "X" option

ROOT
1

The TH1 KS test with “X” option (used in TMVA, I believe) determines its result from throwing N=1000 toys. There is no control to the random seed, so results are not reproducible. Is it possible to add the option to pass it a seed and while we are at it, give the user the option to increase N?
See hep.ucsb.edu/people/claudio/misc/KS_testing.html for an example.

I don’t know if this works, but one thing is to try adding

gRandom->SetSeed(yourseed);

Indeed, that works, I should have thought about it. Still, I think it would be better to provide the seed and the number of toys as an option in the interface. Thanks!
