After a course in ImageJ and doing a lot of tutorials available for QuPath… I am on to the next steps of my mission to be able to analyse images.
In this case, I am having images that are H-DAB. But on some of them, there is some parts outside the tissue that get detected as tissue when I perform " Simple tissue detection ". This area then also contains negative cells after the positive cell detection.
I tried to select the annotation created by the tissue detection and use the brush + ALT to remove those parts of the tissue I do not like, but for some reason, it does not seem to work.
I know I can also adjust the threshold and the min and max area to detect to get this done, but sometimes its impossible to find this for all pictures in the experiment and it is easier and faster to do it with the brush tool.
Do I do something wrong or is this just simply not possible?
Thanks a lot for your answer.
