Inés, I see that you have two classes for values greater and less than 100. This is fine, but if you set processing directive for scale to -10 to 10 then the classifier is unable to distinguish between values that are greater than 100 and less than 100. That is because the scaling is done before the classification. So if you want to control the scaling it should be based on what you need for the classification.
If all you need to do is differentiate between <100 and >100 you could just use SCALE=-900,1100 and set NUM_BUCKETS to some small even number.
