ROIs as import_Kappa plugin


I was using Kappa (version 1.7.3) for curvature analysis.

The Kappa build-in curve fitting doesn’t work well since my curves are really complicated.
So I hope I can import ROIs as curves (this function should be supported in this version 1.7.3). But I couldn’t figure it out. I had a curve ROI in ‘ROI manager’ but there’s no response once I click ‘import ROIs as curves’ in Kappa.

Could anyone provide more detail about how you realize this function?
