TDirectory: creating a folder in a specified path

ROOT
1

Hi everyone,

as the title says, I am trying to create a folder (called Histograms) within a specified path. The only thing is that I have no idea how to implement the path in the TDirectory call:

[code]int a= 1;
int b = 2;

TString path = TString::Format("/Data/%d/%02d", a, b );
TDirectory directory(Histograms);[/code]

Of course, since I have no idea how to add the path, I tried to run the script with just the last line but it tells me that symbol Histograms is not defined in the current scope. Looking at the TDirectory informations, I do not understand why it does not work. I am not sure the TString path line is right either.

Any idea on how to proceed?

Thanks :slight_smile:

Anyway, your previous call should be:
