HyperspyUI for making ROIs in an EMD file and the quantification of the elements

[d1997Gautam]

Hello,
Is it possible to draw ROIs on an EMD file using the Hyperspy GUI and then somehow reading the ROIs and use the quantification() function in hyperspy? I am able to use multiple functions in the ipython console, like decomposition and quantification. However making ROIs is what I am struggling with.
If it is possible to make, store and read the ROIs in the notebook itself using hyperspy/ui, would also be great!
Thank you!

This example should show you how to do that in the ipython console:
https://hyperspy.org/hyperspy-doc/current/auto_examples/region_of_interest/ROI_navigator.html

To store a ROI parameters and restore the ROI:

import hyperspy.api as hs

s = hs.data.two_gaussians()
roi = hs.roi.RectangularROI()

# Add ROI to signal
s.plot()
s_roi = roi.interactive(s, recompute_out_event=None, color='C1')

# Get roi parameters as dictionary
roi_parameters = roi.parameters

# Create new ROI using the dictionary of ROI parameters
roi2 = hs.roi.RectangularROI(**roi_parameters)
s_roi2 = roi2.interactive(s, recompute_out_event=None, color='C2')
