Image stack IHC

Hi there :slight_smile:

I have serial sections from a TMA stained with different (single) antibodies and I would like to stack some of the images so I could visualize if the antibodies overlay or not.
What is the best software to do this?
Any help?
I will need to learn it form the beginning as I have never did this before, so any help is really appreciated!

Thanks a lot!

Best,
Joana
