Hello Slicer support,

For some reason on my desktop computer, there is a problem with recognizing the markups for registration. I tried using both Slicer 4.10.1 and 4.10.2 (the stable versions). This issue has never happened to me before.

Popup message: “Markups must be places first before registration of scans can occur.”

Thank you!

Which extension/module are you using for markup-based registration?
