To do analysis, one should download a copy of the shared library for their particular platform, as well as a copy of the MyEvent package. One must also ensure they have installed the correct version of ROOT for the version of classes you are using. A TBrowser object will have been created which will allow you to browse through the currently created root objects. From the TBrowser window, expand the RInt node, then the ROOT Files node, then the Histograms.root node, and then double click the histogram you would like to view. The MyEvent.c file can be edited to add additional histograms, but the MyEvent.h file should not be modified.
