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):
C:\Users\bellenot\Downloads\test>root

C:\Users\bellenot\Downloads\test>
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__)
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.

root [1]
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?
Thanks very much, it is working now. Much appreciated
