[Insight-users] How to write a DeformableRegistration1 paramater file

[Tessa Sundaram]

Hi Fucang,

There is a sample parameter file under /Insight/Applications/FEM called 
FEMregLMparams.txt.  It accompanies the registration application in the 
same directory called FEMImageRegLM.

DeformableRegistration1.cxx can also be used with the aforementioned 
parameter file.  However, I have not finished writing the documentation 
for the parameter file.  I hope to have that available today or 
tomorrow.  It will be in the /Insight/Examples/Data/ directory, and will 
be called something like FEMRegParams.dat.  

This is still a work in progress, but if you would like to give it a try 
after looking at the parameter file, please feel free to send me other 
questions.
