Hello,
I have a large (50+ bands) stack of backscatter imagery. I have three stacks: one is the raw data, one has a multitemporal filter applied , and one where the stack with the MTF applied has been converted to dB. All stacks are the same size, and each band has backscatter values- I can visualize each band in other programs. I am trying to test different multitemporal filters, but SNAP gives errors when I try to view or perform operations on the raw data stack.
When I try to open any band in the raw stack past band 18, I get the following error:
“Failed to open image view:
java.lang.NullPointerException”
When I view the details of this error, it says:
"A java.util.concurrent.ExecutionException exception has occurred.
java.lang.NullPointerException

In addition to not being able to view most of the bands, I also cannot perform any operations on bands past band 18. I’m not sure what the issue is since I am able to view and work with all the bands in the stack with a MTF already applied. What is going wrong?
