I have been using the curves as semi-landmarks and exporting them as .fscv to be read and processed in R. I recognize the issue with .fscv not holding any data and trying to load those back into Slicer.

I do something along this line. I’ve written a short function in R that reads all of the .fscv files with a “XXXX\_Genus\_species.fscv” from a folder and converts it into an R friendly format. XXXX could represent any set of MarkupFiducials or curve with semi-landmarks. From there, it’s not really that bad to concatenate curves and points.
