    Hi Audrey,

    Unfortunately that is a limitation of the Spot Detector plugin, it’s not really designed to detect spots with important difference in size.

    But you can use the protocol to adapt this and make several spot detection and combine the results. You can see an example with the protocol “Spot Detector scale 2 and scale 3” which is available online. Just type its name in the top search bar of Icy, you should be able to access it 🙂

    Hope that helps !

    Hello Audrey,

    I had the same problem few times ago. What I did to solve this problem was to use different parameters of spot detector on the same image. Found 2 or 3 Spot Detector parameters which could englobe your whole spots (which are also separeted as in your picture) and use the Boolean operation in “Protocol”. The result will be to have different size of spots and for them which are superposed (because they will be detected with both of 2 parameters) they will be merge in one. Hope I help you atleast a bit, good luck for the rest =)
