<h2>DESCRIPTION</h2>
<em>r.li.patchnum</em> is a patch index for r.li program.<br>
It calculates the function <br>
<I> f(sample_area)= Patch_Number </I><br>
This index is calculated using a 4 neighbour algorithm<br>

<h2>EXAMPLES</h2>
To calculate patch number index on map my_map, using 
<em>my_conf</em> configuration file and saving results in
my_out file run:
<div class="code"><pre>
r.li.patchnumber input=my_map conf=my_conf out=my_out
</pre></div>

<h2>NOTES</h2>

An that is full of null values is considered to have zero patch. <br>
If you want to have null values instead run <br>
<div class="code"><pre>
r.null setnull=0 map=my_map
</pre></div>
after index calculation.<br>
