Bug: InSAR deformation changed from SNAP 6 to 7?

[funkenbeachin]

I’m looking at S1 SLC IW for Ridgecrest earthquake. Was v6 changing sign in error? I decided v7 was good based on sense of deformation from:

Measuring Movement from the Ridgecrest Quake

My process chain is here:

Fault Deformation Steps

How is this process for analyzing deformation between 2 S1 passes? [deform] Can I skip the first write/read and run all the processes to snaphu export? Thanks
