How to send to image J just the DAB vector?

Hello!

I have a very quick (and probably basic) question. I have IHC images, and I would like to send to image J just the DAB signal (without the Nissl staining) because I want to measure the % of area ocupied. I am able to see and refine the vector signaling but when I transfer the image to imageJ, the image has DAB and Nissl staining.

Thank you very much for your help!

If you are using QuPath 0.2.0+, have you checked the apply color transforms box?

Or are you asking about how to do this via scripting, en mass?

The Apply color transforms option should be what you need:
