Thomas,

Not sure if this helps you out or not, but here is a function for measuring (separately) an arbitrary number of ROI manager selections listed by index in an array (code below).

toby

newImage("test", "8-bit Black", 128, 128, 1);
makeRectangle(54, 35,10,10);
roiManager("Add");
makeRectangle(70, 70,10,10);
roiManager("Add");

rois = newArray(0, 1);
measureSelections(rois);
exit();

// FUNCTIONS BELOW ================================

function measureSelections(rois) {
  for (i =0; i < rois.length; i++) {
    roiManager("select",rois[i]);
    roiManager("measure");
  }
}

Hi,

Thanks for all the reply, I'm afraid, for my problem, there is no
solution since it does not depend on ImageJ but rather on Java that
manages the List inside the RoiManager. My idea was to select two Rois
and then measure some distances between them via a plugin, so I wanted
the macro to be able to select two rois and then call the plugin. I will
look towards a workaround.

Anyway thanks everybody who helped.

Thomas
