[Insight-users] generating a whole displacement field by combining two halves, generated separately

[Tim Bhatnagar]

Thanks Seth, I like the idea... but with the def fields having pretty much
all of the exact attributes, I was hoping to append the files on a more
macro-scale... however, I think it may require a process like you outlined.

Thanks for the help!
