Problem generating interferograms after Slide assembly is done

Hi there:

I´m trying to do an StaMPS export for a PS processing, but I encountered a problem doing this. My ROI is between two frames, so I do a slice assembly before the corregistration, but I do this step the interferograms generated are completly wrong. If I do the same steps with only one image the results are good. Is this a bug? My processing chain is the following:

Read image -(x2) -> TOPSAR split -(x2)-> apply orbit file -(x2)-> Slice Assembly -> Back geo-coding -> interferogram formation

Any help would be appreciated

Have you tried doing the slice assembly after the interferogram and deburst?
