Ah, sorry, you are correct - those were copy/paste errors!

However, now that those things are fixed
(http://www.rpi.edu/~doriad/Paraview_List/LandmarkFilter/LandmarkTransformFilter.xml)
when I apply the filter in Paraview and set the inputs using the Input
Editor, I get a whole bunch of these errors:

vtkCompositeDataPipeline (0xa82e288): Input port 0 of algorithm
vtkLandmarkTransformFilter(0xa82e240) has 0 connections but is not
optional.
vtkCompositeDataPipeline (0xa82e288): Input port 1 of algorithm
vtkLandmarkTransformFilter(0xa82e240) has 2 connections but is not
repeatable.
etc, etc.

Why would this be?

Thanks,

David
