Hi,

I am trying to write a macro to do some measurements that is limited to thresholded regions. I know I can do it manually by checking Menu -> Analyze->Set Measurements->Limit to Threshold and then Menu-> Analyze -> Measure. However, when I tried to do this in a macro, it does not work.

Here is the macro.

setOption("Limit to Threshold", true);
setThreshold(50,255);
List.setMeasurements;
area = List.getValue("Area");
mean = List.getValue("Mean");
//getRawStatistics(area, mean);
//getStatistics(area, mean);
print(area, mean);
resetThreshold;
setOption("Limit to Threshold", false);

The output values are different from manual measurements. I also tried getRawStatistics and getStatistics. No luck.

So it seems that this setting setOption("Limit to Threshold", true) does not affect the behavior of these measurements in a macro. Or did I do something wrong? Is there a solution?

Any suggestion are appreciated.
