Objective

Test and debug congealing registration implementation in ITK (in NAMIC Sandbox).

Approach, Plan

Initial issue: congealing does not work with recent ITK. The goal is to figure out where the problem is. Run existing tests from sandbox and test on 26-subject FA dataset. Debug.

Progress

We found the following flag is needed to run congealing: ITK_USE_CENTERED_PIXEL_COORDINATES_CONSISTENTLY:BOOL=OFF. We tested the code with existing tests from Serdar and also on a 26-subject FA dataset. We debugged initial crashing problems and patched a bug assuming all input images had the same size. To use this code in its current version however it may be advisable to pad all imput images to the same dimensions.
