When running:

roiManager("Select", 0);
setKeyDown("shift");
roiManager("Select", 1);

the picture ends up with a combination of two ROIs, but when you run the

roiManager("measure");

command afterwards, it only measures one selection.


Try one of the following:
- If you want to have one measurement of the combined ROIs, do:

run("Measure");

- If you want to have measurements for all the ROIs in the manager, do:

roiManager("deselect");
roiManager("measure");



Interestingly, the "Deselect" command doesn't seem to be recorded by the
Macro Recorder.


Hth,
Jan
