Caveats

roi only supports ellipses and rotated boxes

The roi tool only supports infile with the SHAPE column set to ellipse or rotbox.

While the tool may seem to work with some other shapes (circle, annulus, pie), the output likely are not what was intended or expected.

The fovregion and streakregion may be arbitrary regions (polygons, etc).
