OLCI data peocessing
Posted: Fri Mar 26, 2021 11:39 am America/New_York
I am using gpt with OLCI images. I assume that when there are no multiple images, available single image is added to the larger grid specified. Occasionally I see that in the resulting file there is a line appears where no samples are counted! This feature is not seen in the original image. Please see the attached images.

You would need to tell us a lot more for us to understand what you are doing. Judging by the faint semi-transparent compass pattern at the top left of your image it looks like you are doing a screenshot of bands viewed within the GUI.
I do see a dashed line. Based on the Chesapeake Bay scene, that appears consistent with being a meridian (longitude) line.
If you are seeing some other line of missing data, then it could be a screen mapping artifact which would be resolved by zooming in/out or zooming to data/screen pixel matching resolution. The "P" button in the Navigation Controls window.
Note: the best way to export an image is not a screenshot of the GUI window. If you right-click on the image you can then select "Export Image". This tool enables you to not be limited by the monitor resolution.
