I try to use a multi-class BDTG but I cannot set the number of events used for training and testing.
In usual binary BDT I use :
wich does the job. Trying the same thing in BDTG multi-class gives me this error :
: The following options were specified, but could not be interpreted: ‘nTest_Signal=5000:nTest_Background=5000’, please check!
I suppose that this option is not valid in multi-class (and I can understand that) but I do not find an other way that can works within multi-class BDTG.
I am very new in using TMVA and ROOT and I apologize if my question is trivial.
Thanks for your time,
