I am trying to make a script in QuPath version 0.2.3. I found all my cells in a couple of annotations in an image using cell detection. I however want to go one step further and analyse other stuff in those same annotations (and thus exclude my cells).
So my question is, how do I substract these cells from my annotations in such a way I only have my annotations without the cells (thus the annotations with holes in the places where cells are).
I made a small script to convert my cells to annotations, and put them in a hierarchy. But from this point on I am stuck. I cannot find a way to substract these newly made annotations which were the cells from my Parent annotations.
Can someone help me?
