 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

  * status:  new => closed
  * resolution:  => invalid

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.
