Hello
My terminal keeps disappearing on windows when running a TMVA script. I would appreciate some assistance as I am new to root. LowCuts.C (19.9 KB)
Hi,
Which version of ROOT? How do you execute your macro?
It is version 5.34.38
Here is what I get (after fixing your macro):

And I had to add those lines in your macro:
#include "TInterpreter.h"
#include "TMVAGui.C"
And replace the not by ! on this line:
#if !defined(__CINT__) || defined(__MAKECINT__)
I have made the changes but it still disappears just few lines after the last line on the screenshot.
You still didn’t tell how you start root.exe…
By clicking on the root app icon and the terminal appears on the screen.
OK, so please open a command prompt and start root from there, so you will see the error message, if any…
I now get the error you got after you fixed those few lines even though I have the two root files it is complaining about.

Are those files in the same directory than the macro is? Or in the current directory?
They are just outside the macros folder but I have tried running the macro with the files in the same directory too and it still failed. I removed the “./” in front of the file names when running it from the same directory.
Could you put all your files and macros in a common directory and start root from there?
