I can't tell if I am misunderstanding this, but why not just find the spots
first, then get their coordinates (eg their XStart Ystart points, or their
centroids if they are convex, then check in the original image with each grid
cell labelled uniquely, to which label corresponds each spot coordinate pairs.
That way you have both the coordinates and the grid cell they are in and you
can also know how many spots each cell has.
Is that what you were after?
Cheers
Gabriel
