+===== Accessing the chain =====
+All the trees in the chain can be accessed the same way as it is done with trees, for example:
+<code>
+myChain->Draw("B_M");
+</code>
+to make a histogram with the B-mass.
+**Note**: The first time you access the chain in a ROOT session, it takes a little longer, as the file has to be checked (there is a way around this, but it hasn't worked
+out yet...)
