Importing ROI from Kappa

I am having trouble importing ROIs from ROI Manager for Kappa. Whenever I click “Import ROI as curves”, no further options pop up. I then selected “Load Curve” data to try and upload ROI through this option, but the curves did not show up in the program.

How can I resolve this issue?

What kind of ROIs do you have in the ROIManager? And also do you see any error message?

Hi hadim, the ROIs are from the curves in “Simple Neurite Tracer”. No error message is being shown, although no curves are showing up in Kappa.
