hello, i need some urgent help here, the problem i'm having is that after i've mosaicked my data strips using the 'feathering' method, and run classification on the whole mosaicked data, I got an error message - some sort of 'array error' - the classification was halted at 90%. but, if i mosaicked without using feathering, i can run the whole mosaicked data without this error. But i need to use data with mosaicked (feathering) due to better image quality. anyone had encountered similar problem? Any help is highly appreciated. Ben
