Hi Andrew, thanks for reporting this issue. We are more than happy to work with you and get your hyperspectral image (426 bands) working in our image classification tool. First of all, may I know please which hyperspectral data did you use and saw this issue? If you could share with us a small area of your data (e.g., 1000 by 1000, but has to keep same number of bands) for testing the fix of this issue, that will be great. If you could not, it is also fine, we will try to find similar hyperspectral data for testing. You could contact me directly through my Esri email: Ling_tang@esri.com. Thanks and I am looking forward to your reply.
