Realized this got sent to insight-dev's which I'm not a part of, so it
bounced it back. Forwarding so that it's tracked in insight-users.

You'll have to forgive me; I'm a video editor by trade and have been at a
steep learning curve to get this far into the troubleshooting. Let me make
sure I understand. Essentially, the disparate ppi's in my images are
causing my issue. If, just by example, all of my images were set to the
same ppi, things should work correctly. My use of JPEGs caused the
difference of outputs that I was interpreting as correct behavior.
Assuming this is the concept, I went back and ran a test from my original
TIF images (they're in the 100MB range so I wasn't using them before). I
changed everything to 72 ppi in Photoshop without resampling so that every
image had the same dimensions as before, then ran LandmarkWarping2 again.
This time, 4.3.2 and 4.4.0 did produce the same output, but it didn't
produce a correct output, at least not how I understand Landmark Warping
should work. This is what that output yielded:
https://dl.dropboxusercontent.com/u/13015285/Chad-4.4.0-005.jpg (Note: This
is a jpeg made from the output tif, just to cut down on filesize).
It seems as if the output is at the appropriate scale, but it obviously is
not in the expected spot. Am I just missing something in the concept of
landmark warping, did I not understand that voxel spacing concept, or is
there something else going on?
Thank you all so much for your help. I'm going to try the suggested
"SetOutputParameters" change, too, to see what happens.
