switch a ROI in javascript

[lechristophe]

Hi,

I'm writing a script (js) that takes a ROI in the ROI manager, process it,
and generates a new ROI. I'd like to replace the input ROI by the output
ROI in the ROI manager at the same place, but with a modified name. Do you
know what is the easiest way to do that?

Thanks for your help,

Christophe

The Javascript below should get you started. Hope that helps.

// printing some output to the Console window
log.info("Now replacing ROI '" + roi.getName() +

imp.setRoi(71,201,32,20)
rm.runCommand("Update")
