Hi
    I am new to iamgeJ Macro. I am trying to automatically measure multiple ROIs and color then basing on the measurement.
    However, I do not know how to catch the returns of the measure function:
for example:
   

      roiManager("Measure");

returns a series of measurement including "label, Area, Mean, IntDen"
     What script can I use to catch the "Area" and "Mean“ value into a variable?

Many thanks for your help.
