Well, that's what I call an informative error message :)

I would then probably try both ways and compare the results. If they are
identical, it does not. If there are differences exceeding what one
would expect from rounding errors, it does. I am now using four images
but if I remember correctly I used to have three and then submitted the
first magnitude and the phase difference map and it seemed to work ok.
Hope this helps,
Marko
