I have quantified cells in my images (3 images per animal, n=3). I have exported the results to an excel sheet from the Image J "summary" box you get you use the "Analyze particles" option in the end. Now, i am struggling how to make sense these numbers you have in the Image J "summary" box as "Count, Total Area, Average size, % Area, Mean". How to get a count per unit area calculation from here. I want to interpret these numbers scientifically in my paper. I welcome your suggestions. Thank you.
