Hello!
I’m having a problem with watershedding. I want to break up clumps of particles, but I don’t want to break up the empty circles in the image. Any suggestions?
Thanks!

Try a Process > Binary > Fill Holes before doing the watershed. (You can keep the original mask to recover the circles later.)

If that doesn’t help, please show an example image illustrating your issue.
