I'm trying to perform a supervised classification using i.class. I'm then using i.maxlik, but this is returning the following error:
GRASS 6.4.3svn (India_01):~ > i.maxlik group=test_group@test subgroup=test_group sigfile=test_sigfiles1 class=test_results1 ERROR: Unable to read signature file <test_sigfiles1>
I'm not sure what other information I should provide. Can anyone suggest the possible reasons for this error? I've tried using i.cluster to generate an unsupervised signature file, and i.maxlik reads this perfectly well.
