This is a GUI that allows you to manage multiple ROI handles.
  After you have an image open, call ROImanager from command line. A window will popup to ask you which figure to process. Click done after you make selection.
  Click 'New ROI' to make a freehand ROI selection. Once you're done with selection and double click, you should see a new ROI name pop in the listbox. To delete an ROI, select from the listbox and click 'Delete ROI'.

  Click 'Export ROI handles' to export a cell array containing all the ROI handles to base workspace.

I'd like it even better if one could export the ROI vectors/coordinates so one would be able to use them elsewhere (the next image i.e.).

Thanks for pointing that out, Jamie. Indeed it's due to changes made in R2014b. I've modified the codes. Now it should work in both R2014b and earlier version.

handles.output = handles.figHandleList(handles.idx);

Error in gui_mainfcn (line 95)

Error in chooseFigure (line 42)
gui_mainfcn(gui_State, varargin{:});
