[TMVA-users] FATAL error for LLH training

[Marcus M. <mar...@tu...>]

Dear experts,

I have a problem while using TMVA, which I do not really understand. I
perform a Likelihood and BDT analysis within different pT bins and with
different signal and background samples. In general this works fine, but
for the first pT bin, which has the most statistics, I get the following
error for the LLH:

--- <FATAL> Tools: Trying to read non-existing attribute 'Method' from
xml node '

For the other bins it works fine. If I exclude one of the signal
training samples (unfortunately the one with the most statistic) it
works fine. Also BDT works fine in all cases. I also checked the xml
file, but could not find any hint.
I use TMVA 4.1.0 coming with root 5.28/00.

Do you have any idea what is going on?

Many thanks in advance!

Cheers,

Marcus
