Hi Gonzalo,<br>
<br>
you wrote:<br>
&lt;what is the difference between the obsolete IDL procedure
&quot;kmeans&quot; and the<br>
&lt;new &quot;cluster&quot; ?... In theory, with this procedures we get
the same results, but<br>
&lt;I tested it with the same input parameters (same image, quantity of
clusters,<br>
&lt;etc, etc), and we got different results...<br>
<br>
I haven't responded to your earlier post of this question because I don't
know the answer. In the last few days, I've managed to solve my problems
with the CLUSTER function by not using it! I've downloaded a program
written by Vincent Schmithorst called CCHIPS/IDL and there's a procedure
in this program package called ksegment.pro which I've modified and am
now using for my cluster analysis. And it works well!!<br>
