Then it is normal that all pixels will be in the same class. You could ask i.maxlik to output the reject map and then define a threshold in that map as a mask to show those areas whose probability of being in the class is sufficiently high.

[GRASS-user] i.maxlik yellow map
Hi Users, I have created a signature file in the g.gui.iclass (supervised classification module) and it looks correct in 'preview' and when i inspected the 'sig' file. When the signature is applied using 'i.maxlik' the result is a solid yellow colour as a layer. What could have gone wrong? Thanks, -- *Paul J.
