 To compare the distribution of bonded terms, we must first rerun PyCGTOOL to generate samples of the bonded measurements.
 For the atomistic reference simulation, this can be done by running::
 
-    pycgtool.py -g atenolol.gro -x atenolol.xtc -m atenolol.map -b atenolol.bnd --advanced
+    pycgtool.py -g ref.gro -x ref.xtc -m atenolol.map -b atenolol.bnd --advanced
 
 In the menu, set the advanced option `dump_measurements` to `True` by selecting it with the arrow keys and toggling with the enter key.
 Once this option has been set, continue by pressing the q key.
