[ROOT] Ntuple trouble

I am attempting to use root to process a large data set where each entry has
8 variables.  To do this, I created an ntuple using the TNtuple class and
wrote it to a file.  I am able to read the file back into root.  However, I
cannot figure out how to extract specific values from the TNtuple object.
I need to access the specific values for each variable, one entry at a time.
I have searched the ROOT website to no avail.  Any assistance you can give
would be appreciated.  Thank you.
