As a followup, it looks like changing the minimum cluster size may reduce the number of final clusters, but the final number seem not to exceed the initial number.

I'm trying out GRASS's unsupervised classification functions. As I understand it, it is a 2 step process.
<div class=""><br class="">
</div>
<div class="">1. run i.cluster to get cluster signatures</div>
<div class="">2. run i.maxlik using the cluster signatures to generate the spatial clusters</div>
<div class=""><br class="">
</div>
<div class="">I've varied the parameters several times, and AFAICT, setting the initial number of clusters also determines the final number. In other unsupervised clustering routines I've used, this is not the case. Because the clustering iterates until the
convergence value is reached, the final number of clusters can be different from the initial number. Can anyone offer insight on this for GRASS?</div>
