Dear Hayato

If you just want to measure all ROIs and nothing else than:

----------------------------------
roiManager("Deselect");
roiManager("Measure");
----------------------------------

should do the job. If no ROIs are selected in the ROI Manager than all are used when you use roiManager("Measure");

Best wishes

Kees

Dear all,

I'd like to measure all ROIs (200000~500000) using the macro.
So, I performed the macro referred to the past post as below.

----------------------------------
count=roiManager("count");
array=newArray(count);
for(i=0; i<count;i++) {
        array[i] = i;
}
roiManager("Select", array);
roiManager("Measure");
----------------------------------

But it worked very slow compared with the method manually select all ROIs
and put on the "Measure" button on ROI Manager.

Because I have to measure many slices (each has 200000~500000 ROIs), I'd
like to use the macro.
How should I do macro as fast as the manual method?

Sincerely,
Hayato
