</div>this looks really very promising!<br>
<br>
Of course the results depend a lot on the input spectra which are<br>
sometimes not easy to obtain. You need to identify pure pixels<br>
which one can find the the corners of the PCA featurespace. When<br>
time, I can translate my German instructions to English.<br>

Wonderful.<br>
For the GRASS 6 version, could you please update or patch against<br>
grass-addons/grass6/imagery/i.spec.unmix/<br>
?<br>
<br>

<br>
Great!<br>
<br>
Thanks for your hard work,<br>
