</div>How did you do this? (which commands)?<br>

</div>Yes please :)<br>
<br></blockquote><div><br></div><div>Eheheeh here goes :)</div><div>I have 4 bands and in each one pixel values are calculated based on band cluster mean. I mean, pixels included in a certain cluster, are all with the same value that correspond with average of pixels included in the same cluster. This happens in all 4 bands. What I want is to merge 4 bands in a single one in which I will have labeled clusters with an integer (1,2,3,4,5...) isntead of pixel mean.</div>
<div><br></div><div>How can I do this merge?</div><div><br></div><div>Thanks Monica</div></div>
