An error when using graph builder to calculate one image divided by another image

Microwave Toolbox
#1

Hi,

I want to use graph builder to calculate VV/VH, where both of polarization are from the same image. I build the graph like this:

47%20PM

and my Bandwidth expression is this:

           Sigma0_VV/Sigma0_VH

But i have this error at the end:
23%20PM

Do you have an idea how should i change my graph?

Thanks！
Paul

For me it works - try to manipulate with the SNAP performance parameters, the reason of your error could be you have not enough memory.
Or simply divide your graph into two smaller graphs - that should help.
