[Paraview] different orientation of input files

[Tom Schoenemann]

Hi everyone,

I have a question about changing/editing the orientation and origin information about an input file.  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.

Originally, both files had the same orientation and origin: ITK-SNAP used the same file to create the beautiful surface that the stats were created with.  

So Paraview apparently does not read the header info the same way for the two types of files, even though ITK-SNAP does.  

Is there a way to change the origin and/or orientation of files in Paraview?  I'm assuming there is a simple transform I could figure out by trial and error to get them to overlap again, but I don't know how or where I would do this.

Thanks for any suggestions!

-Tom
