I ran i.gensigset to make the training map for SMAP-classification but I had some errors: 
...
4 classes found
Reading raster maps...
Clustering class 1 (399 pixels)...
Number of subclasses is 2
Clustering class 2 (105 pixels)...
Removed a singular subsignature number 10 (14 remain)
...
Too many subclasses for class index 4
Number of subclasses set to 1
Number of subclasses is 1
unable to create signature file testsig for subgroup smap of group aster2007 at test
Unable to create signature file <testsig>

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