Usage: <tt>input = [ <i>pn  id</i> ] copyPathtoS</tt>

<p>
Copy the spin configuration from the path to array <tt>S</tt>.
There are three paths in the MD++/ising model: <tt>pathA</tt>, <tt>pathB</tt>, <tt>pathC</tt>.
Which one gets chosen by <tt>copyPathtoS</tt> depends on the value of <tt><i>pn</i></tt>
(1 for <tt>pathA</tt>, 2 for <tt>pathB</tt>, 3 for <tt>pathC</tt>).
<tt><i>id</i></tt> specifies which configuration along the chosen path will be copied.
