<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>Processing PNG files in i.maxlik (Windows-based GRASS), I got (and keep
getting) the </DIV>
<DIV>following message:</DIV>
<DIV> </DIV>
<BLOCKQUOTE style="MARGIN-RIGHT: 0px" dir=ltr>

<DIV>i.maxlik group=sattar@user1 subgroup=subgroup
sigfile=unsupervised_signature </DIV>
<DIV>class=unsupervised_map</DIV>
<DIV>ERROR: Unable to open signature file <unsupervised_signature></DIV>
<DIV>(Mon May 20 09:22:53 2013) Command finished (0 sec)"</DIV></BLOCKQUOTE>
<DIV><FONT size=4></FONT> </DIV>
<DIV>I am trying to produce an unsupervised classification, but keep getting
hung </DIV>
<DIV>up in 'i.maxlik'. I have tried reloading the latest version of Grass along
</DIV>
<DIV>with the 'visual' software, but no luck - I seem to be stuck! I can see
from </DIV>
<DIV>the email exchanges that you are all very busy, but I would be grateful if
</DIV>
<DIV>someone could help me to move on.</DIV>
<DIV> </DIV>
<DIV>Many thanks,</DIV>
<DIV> </DIV>
