Hi,

I have a macro that runs a binary mask of a stack to generate ROIs within a polygon. Sometime when the macro runs, two or three ROIs are generated per slice rather than just one. Is there a way that you can force ImageJ to select only the largest ROI and ignore/delete the others. I need to extract one ROI per slice.

Many thanks
