Following error

based on your screenshots you created a subset. Did you save it as BEAM DIMAP format? Otherwise some of the metadata gets lost.

Thanks for reply,
Now am getting another error while applying orbit file as shown in the screen shots. basically I am new to this. I am trying to detect the ship from ocean application. I have download the sentinel data following the webinar Rus: ship detection with sentinel -1. Accordingly I have downloaded & installed snap 6.0, Download image data as shown in the webinar & trying to do the same process but could not proceed further. Is there any alternate solution / procedure for this ? form where I can get or access step by step process?
