Speckle filtering produces NullPointerException

s1tbx
#1

I’m trying to apply speckle filtering to S1 IW SLC data. I have split, applied orbit file, calibrated to complex output, deburst, merged, C2 matrix generated, and multilooked to square pixel. Now, any speckle filter I apply produces the NullPointerException. I’ve run this process successfully before and I just reinstalled SNAP so I wonder if it’s a bug in an updated version?

Well, SNAP just did a big update and now the problem is totally fixed. Thanks to everyone who did that, even though I don’t know who you are!
