I am using the (undocumented) function DISP_ROI_TOOL_INIT to launch the ROI tool and display ROIs from a script. When I have two display groups open (with images of the same dimensions), I can not find out how to make a certain ROI show in only one of the display groups. Can anybody help me? I.e., I would like to show different ROIs in different display groups, and not all ROIs in all display groups.
