StripmapApp interferogram geocode error

[jsidhu45]

Hi,

I am new to SAR processing using ISCE2. I was following the InSAR pair processing with stripmapApp notebook for learing the processing workflow. I was able to exceute almost all the commands, but met with an error on last step of interferogram geocode.

stripmapApp.py stripmapApp.xml --start=geocode  --end=geocode

You have to complete all the steps before the geocoding before running the geocode step. It looks like it is not finding one of the files that should have been created by a previous step.
