 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

 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
