ROI Registration Non-Functional

I am trying to use ROI registration (within the surface registration module) to register two .ply models based on an overlapping section of the models after fiducial registration (which gave close pre-alignment).


I have placed the fiducials to border the overlapping region with both the markups module and the built-in landmark functionality in the ROI registration module.

After placing the fiducials and setting an output transform, the module does not run to completion/register the models when I click compute (a previous attempt turned the models blue but also did not work).

Error log:
