I would like to ask about the percent of change parameter of the unsupervised class function of envi. It's just that I can't monitor how much percentage the processing has reached. All I see is the progress of the iterations that are being done. Well, i guess im very impatient. ERmapper, on the other hand, you can see the progress status, it has its own dialogue window, so you can see if it is reaching the desired percentage unchanged (its percentage change in envi). Could somebody enlighten me with this area of concern. thanks
