Greetings Patricia!
"I think I can achieve what I want ... But I don't know how to go about it."
Aha!
Maybe this macro does what you like to obtain:
//
setBackgroundColor(0,0,0);
setOption("BlackBackground",true);
run("Blobs (25K)");
run("Invert LUT");
setAutoThreshold("Default dark");
run("Analyze Particles...", "add");
roiManager("Select",Array.getSequence(roiManager("size")));
roiManager("Combine");
run("Clear Outside");
resetThreshold;
roiManager("Show None");
exit();
//
Regards
Herbie

Hello everyone
I'd like to simplify some images so that I can measure the areas of interest.
Using a series of Thresholdings, I think I can achieve what I want ...
But I don't know how to go about it. In fact, with Analyse Particles, ROIs are
generated and I would like, for example, to either remove the content of all
the ROIs from the image or Clear Outside.
My problem is that I don't know how to select all the ROIs at the same time and
when I try Clear Outside, everything outside the first ROI is deleted ...
With Blobs for example, I'd like to remove all the white background. Invert LUT
/ Threshold selects all black shapes. But now I don't know what to do with the
ROI Manager generated by Analyze Particles.
Is what I want to do possible?
If so, can any of you help me write the command lines?
Many thanks in advance for your help
Patricia
