Snaphu plugin for SNAP

[ABraun]

please don’t distribute your questions over multiple topics.
I recommended multi-looking in the other topic (because of the file size) and asked for a screenshot of the interferogram:

How to Install SNAPHU on Mac OSX and Windows for Unwrapping InSAR Images?

depending on the type of deformation, multi-looking might be an option. How does your interferogram look like? 20x20 m will still allow most analyses and significantly reduces the file size. But as I said, the error message was propably not caused by the size.
