Anthony,
Thanks for your sugestion - this would require to write a plugin which I do
not know how to do. I thought there might be a way to do it with the features
already available in Image J.

Cosmin,
If I understand your question correctly, you could simply write some
statement like:
for (n = 1; n <= nSlices; n++)
setPixel(c, r, theValue);
theValue would just be some value that would guarantee that that pixel
would be thresholded out every time. Unfortunately I think you may have
to threshold each slice 1 by 1 if you wanted to do this. That's the
first thing that comes to my head, but maybe there are better ways to do
it.
