Hi,

I have 3 questions about cmtk alignment.

1) Landmark Alignments
Is there a workflow example on using landmark based alignments?  I did not find one on the documentation pdf and was wondering about this.
 
2) What is the output of the .xform files
I was hoping to understand the output of the .xform files that get generated with the transformations.  The ultimate aim would be to be able to generate a movie of one brain transforming into another and I was hoping to be able to create a one-parameter flow between the sample and the reference brain.  is there a way of doing this?

3) Is it possible to use a subsampled stack to find a transformation between two brains and then apply this to the original stack?  I am thinking about ease (and possibility) of computation without running into out of memory errors.

Any help on where I can find any documentation or examples would be great.  Thanks.
