First you need to have fastjet (version above 3.0) installed.
Next, copy the two files HEPTopTagger.hh and HEPTopTagger.cc under the directory:(fastjet-install-dir)/include/fastjet/tools/
Now you are ready to use HEPTopTagger!

To make example_heptoptagger_for_fj3, you can use the command (you might need to define appropriate environment variables in makefile).

>make


Then you will get the executable example_heptoptagger_for_fj3 and execute it with 

>./example_heptoptagger_for_fj3


Then you will get two files:

sample_event_out.dat
sample_event_display.dat


You can check if they are identical with the files found in results_ref/
If you have gnuplot, launch gnuplot and type

>load "sample_gnuplot_display.dat"

will give you the event display.
