Respected Sir, I am using erdas imagine 2011. I am using knowledge engineer for my classification. I have added the value for rule1 in hypothesis. When I open a new rule in that same hypothesis, in the value column the "other" option in not working. Therefore I am unable to insert desired numeric value in it. I have tried to give the screenshot of the problem. But the forum is not allowing it. I need help. If you give me your email id I will send you the screenshot of the problem. Thanks in advance.
