Cannot display anything

I have installed root 5.20 on my Ubuntu machine. I launched a simulation and my folder first.root was created. Then i launched root by typing : “root first.root” Root launches correctly but I can only have it in my terminal. I remember that there is a graphical option to get root in a window which is much easier.
Anyway I dont know how i can display anything I have tried to lload by .L but i get errors.
I am new with root so… could you help me please.

You need to have a look at the different tutorials first. You should also get the manual for root 5.20 and look inside.

What you are looking for is the TBrowser.


thank you but i dont see what i can do with those tutorials… :blush:

I get to this step but i dont know what to do next.

ROOT 5.20/00 (trunk@24524, Aug 26 2008, 12:44:00 on linux)

CINT/ROOT C/C++ Interpreter version 5.16.29, Jan 08, 2008
Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.
root [0]

I dont get why I get errors by the way… do you?

Is this message "macro analyse.C not found " not clear enough ?


okay that is not clear to me sorry!
i dont get why root cannot find analyse.C.

[quote]i dont get why root cannot find analyse.C[/quote]Because it is not in the current directory (or is not readable) nor in any of the other directory root has been told to look into. Where is this file in relation to your current directory?
