TOPS coregistration problem

Microwave Toolbox
1

Greetings!

I am trying to re-do an interferometry turorial to my chosen area based on this tutorial:
http://seom.esa.int/landtraining2015/files/Day_4/D4P1a_LTC2015.pdf

I have a dataset from 2015 and 2019, they are both S1A - IW - SLC format.
However, after TOPS coregistration finishes, the slave intensity band is always a grey blank image

The setting of the TOPS coregistration are the same as in the tutorial

If I try to make the next step, which is Interferogram Formation, the following error pops up:

I don’t know if this is because of the coregistration or just another totally independent error.

My question is what am I doing wrong and why is it not working.

Thanks for the help in advance!

Try to use SRTM HD 1sec auto-download instead of 3sec, and check this box
