Workflow between SNAP and StaMPS

Dear sir, Sorry to bother you again. And thank you very much for replying me. I’ve select DEM HGT 1Sec while interfergram making. If I do not terrian corrected the interferogram and just try to make StaMPS export, the following error is showing:

If I do terrian correction then following error is showing:

What should I do now? And the area I’ve chosen for finding interferogram, there are only 11 images with same frame and path. Will it be worked with 11images? If I take 11 images, should I make 1 master and 10 slaves for co-registration?
I’m really very sorry to bother you. I’m a beginner in this sector. I’ve read the previous post of you and ALOS PALSAR processing this post too. It will be very kind of you, if you help me.
