I ran i.gensigset to make the training map for SMAP-classification but I
had some errors:

...[[BR]]
4 classes found[[BR]]
Reading raster maps...[[BR]]
Clustering class 1 (399 pixels)...[[BR]]
Number of subclasses is 2[[BR]]
Clustering class 2 (105 pixels)...[[BR]]
Removed a singular subsignature number 10 (14 remain)[[BR]]
...[[BR]]
Too many subclasses for class index 4[[BR]]
Number of subclasses set to 1[[BR]]
Number of subclasses is 1[[BR]]
unable to create signature file testsig for subgroup smap of group
aster2007@test[[BR]]
Unable to create signature file <testsig>[[BR]]

Why I had these errors? What will I do to correct?
Thanks

Comment:

Please check that the training areas are not too small. From my
experience this warning appears with too few pixels in a training area.
