Hello

I've searched through the archives, and I haven't find a clue about this (or
it might be I'm not enough thorough):
Is there an easy/elegant way to random select x ROIs for measurement? Eg. I
have around 230 ROIs, but I need only 200 results for the statistical
analysis. Sure, I could select exactly 200 from the ROI manager, but that
has the opportunity that I might unintendedly "sort" them - this is not
exact randomness.
I think this could be easily done with a macro/plugin, unfortunately I can't
program (though I see in case I'd like to seriously work with this
application I'll need to pick up some Java skills).
Thank you

Regards

Ákos
