Malfunction of Phase to Height and Coherence Estimation - Interferometric

Hi there,

maybe it is my fault but I do not get results after running the processes “Phase to Height” or “Coherence Estimation”.
I work with S1TBX Version 4.0.2 and SNAP 4.0.2

After opening one of the tools I kept the default values (even the suggested target product name like “insar_coregistered_stack_ifg_coh”) and just clicked on run. Shortly the processing bar appears and disappears immediately and no file was created.

I experienced this behavior with data of my study area as well as with data from SARedu (SARedu Tutorial ID 3102 - Deformation monitoring with InSAR).

Did someone experienced the same problems or are there any solutions?
