[Paraview] [EXTERNAL] different orientation of input files

[Tom Schoenemann]

OK, that worked. I've figured out how it works, following what you suggested.

Unfortunately, Paraview didn't just shift the data over, leaving it in the same orientation, it also inexplicably changed the orientation by several degrees (??).  Even if I am able to get the two boxes in basically the same location, the shifted orientation makes it impossible to be confident the data are overlaid in the right places.  This is very frustrating.  Apparently Paraview makes random changes to the orientation??  Why on earth would it do that?

Not sure what that would be useful for, but in any case, I need to move the contour and/or data within the workspace, so the two overlap.  Transform is only changing the box, not changing the location of the object within the box.  Again, maybe I'm missing something.

Basically, the problem is this: I have a 3D volume (originally voxel data) file that contains statistics on its surface that I want to display color-coded.  I can create a nice smoothed version of the surface using a different piece of software (ITK-SNAP), and this is the surface I'd like to use to display my stats (Paraview does not allow you to smooth the surface in the same way that ITK-SNAP does, eliminating the stair-step surface artifacts).  I can indeed read both the stats file and the surface file from ITK-SNAP into Paraview, but unfortunately they now have different origins. That is, they don't overlap (the bounding box for the stats is completely outside the surface model that ITK-SNAP created.
