#2464: g.gui.iclass: show output of signature creation
------------------------------------+---------------------------------------
Reporter: mlennert | Owner: grass-dev@…
Type: enhancement | Status: new
Priority: normal | Milestone: 7.1.0
Component: wxGUI | Version: svn-releasebranch70
Keywords: g.gui.iclass signature | Platform: Unspecified
Cpu: Unspecified |
------------------------------------+---------------------------------------
Sometimes, when training areas are not good enough, trying to create a
maxlik signature file provokes messages such as "Signature X not
invertible". Then trying to run i.maxlik on that signature file, you get
the message "Unable to read signature file" (why that has to be so is a
different question). So when you see the "not invertible" message, you
know that you have to improve the training areas (or use a different image
group).
However when you use g.gui.iclass, you never see the output of i.gensig
and so you just go on and then get the i.maxlik message without
understanging why. g.gui.iclass should allow the user to see the i.gensig
output.
