get_spec_from_ellipse_params crashing.

[TrystanScottLambert]

Hi. sorry to add another issue but we seem to have a problem with get_spec_from_ellipse_params not working. When we run it we get a IndexError in the draw_pyregion function.

I think that is because eventually the function:

draw_pyregion()

is called.

Where the function is defined you have

   fig = plt.figure(self.n)
   ax = fig.axes[0]

In lines 647 and 648. fig.axes[0] is always going to result in an IndexError in this case because fig.axes is empty. Am I missing something?

Thanks.

When you load the cube, PyMUSE open an figure that shows the white image. Do not close that figure when you extract an spectrum. The error seems to occur because PyMUSE wants to draw the aperture in that figure, but the figure is close, so there are no axes. You can also reopen it using cube.reload_canvas()
