Setting the slice of an ROI

[Jonathan Jackson-2]

Dear List,

This is a question about using ROI's on an image stack in a macro.

I would like to take an ROI that was created on slice 1 and change / update
/ duplicate it so that I have the same ROI but linked to a different slice.
Starting with an ROI in the ROI Manager, on slice 1 of a 4 slice stack, I
ran this code

roiManager("Select", 0);
setSlice(3);
roiManager("Add");

but the new ROI was also attached to slice 1.  Can anyone suggest a way to
change the ROI's slice?

Thanks,
Jon

This is a bug that will be fixed in ImageJ 1.37b.
