*Dear All,*
**
*Sorry to bother.  I want to fit an ellipse and draw it to my ROI.  I found
that there is a EllipseFitter class.  But it is not in the menu of ImageJ.
Anyone knows how to run EllipseFitter in a macro, if I have chose the ROI
with XCoordinates and YCoordinates?  I am looking for some macro like
**run("EllipseFitter",
xarr,yarr);, but it does not work.  *
**
*The EllipseFitter only works for closed ROI.  For a set of (xarr,yarr), how
to fit an ellipse if the points are discrete?  *
**
*Thanks a lot,*
