[Insight-users] MI Registration

[Shannon Hastings]

I am just starting to play with the MI Registration Metric I am having 
some trouble getting any good results.  I am for starters just trying to 
get it to register the same volume correctly with itself.  This volume 
is a set of PGM images.  The algorithm seems to always return some 
rotation in Z even though it is trying to register against the same 
data.  I would think that it should return a transform back that is 
close to zero.  Anyone have any idea?
