Hi,
What kind of data does your ROOT file contain?
Is it histograms or rather columnar data (ntuple, tree)?
You can find information about basic ROOT I/O in this course:
Look for “Reading and writing data” and “The ROOT columnar format”.
I can point you to more information once I know about what exactly you need to do.
If your ROOT file is not too big you can post it here or give a link to download place you can put it on.
