Dear All,

I want to convert a segmented-line into an area, and repeat this for different line witdths (of the same original segmented line). I can do this manually, but I fail doing this from a macro. Below is a macro which I thought would do this, but it fails. All created areas have the same size.
What am I missing?

Thanks
Martin

run("Dot Blot (7K)");
makeLine(482,48,387,125,246,90,156,175,67,143,54,223);
roiManager("Add");

for (i=1; i<33; i=i+10) {
        roiManager("Select", 0);
        run("Line Width...", "line="+i);
        run("Line to Area");
        roiManager("Add");
}
roiManager("Show All");
