Open all your granular in Product Explorer, and then add all opened in the Batch processor, using the highlighted sign, or drag and drop those opened in the Batch processing.
I think you intend to subset the same AOI for all! in this case you could use google earth to delineate your AOI as wkt, and then paste it one time in here,
Now it is showing another problem which I really don’t get cause I did my subsetting all together with 10 images simultaneously. So all have same raster size and the same pixel size as well
And technically according to the operator, it compares too many indices, So inclusively many indices would be calculated using the aforementioned bands,
Then it’s my bad. First, I thought they showed it for an example. so if I have 4 bands at least it will work. Second, I am analysing the images with these (2,3,4,and 8) bands only. So it will not work for me, I guess.
Will try QGIS then. Thanks. It was so helpful to chat with you. Come back later with some other problems
