Reading part of a text file


I have a couple of text files containing data, but all files contain a description of my simulations in the beginning. Is there a way to tell ROOT to read the files beginning in a specific line so it could ignore the descriptions?

I annexed an example. I would like to tell ROOT to read data beginning at line 36.

Thanks a lot for the help.

This is a C++ question more than a ROOT question. You’ll have to read your file skipping the first 35 lines.
You can get an idea about how to achieve that here

Looking at your file it seems readable in a TTree using:

TTree::ReadFile: … f1d3bdc120

(TTree::ReadFile ignores the line starting with #)
