Dear experts,
I am writing to report some bugs that I have noticed in TMVAMultiClassGui
The relevant ROOT Version is 6.22.02. I am invoking it on lxplus using
source /cvmfs/sft.cern.ch/lcg/app/releases/ROOT/6.22.02/x86_64-centos7-gcc48-opt/bin/thisroot.sh
I am placing the output ROOT file from training in my public directory on lxplus at
/afs/cern.ch/user/a/avenkate/public/forTMVA/TMVA_Comb_noCV_split.root
Upon doing
root -l
root [0] TMVA::TMVAMultiClassGui("TMVA_Comb_noCV_split.root")
I notice the folowing:
-
Buttons 4b - Drawing of Classifier Output Distributions for Training and Testing samples superimposed : I am unable to interactively right click on the components drawn on the canvases and change attributes like line color, fill color etc, AFTER zooming in on a canvas. The individual TH1F objects are just not selectable. Even before zooming in, only the training histograms appear to be selectable, not the testing ones.
I can also see this effect in view->Event Statusbar. When I hover my mouse over the objects after zooming, their names don’t show up on the status bar. Instead, I just see the name of the canvas. -
Button 4a - Drawing of Classifier Output Distributions for Testing sample alone - None of the objects drawn on the canvas are selectable, even before zooming in. Only the frame itself gets selected every time I right click.
-
Buttons 5 and 6 - ROC Curves - For one vs rest (Button 5), only one of the canvases drawn actually has a ROC curve. The rest are empty. For one vs one, again only a few canvases have ROC curves. The rest are empty.
I wished to bring these to your attention. I would be happy to provide any more info that is needed from my side.
Arvind.
