I am trying to use TTree::ReadFile to create a tree from a rather large text file containing > 10 million rows. This can take some time, so I was hoping there was a way to have the method print out a status message every X number of rows so that I now it is running as expected. I looked in the source code for TTree::ReadStream and found that if I set gDebug > 2, it would print on every line. This is an excessive amount of printing, however. Does anybody know if there is a simple way to get the method to print status messages occasionally?
