<DIV><FONT color=#000080> Many thanks for your
help in DiffeoMap. I have got to know how to use the output matrix of
Landmark-based Affine registration.</FONT></DIV>
<DIV><FONT color=#000080></FONT> </DIV>
<DIV><FONT color=#000080> Today, I did Landmark-based LDDMM.
The parameters were shown in the attached figure. I noticed two files
(LDDMMMatrix.dat and LDDMMMatrix.hdr) had been saved in my folder. In my
case, the template and the subject 3D images are
both 256x256x512 (~32 MB). But the output data LDDMMMatrix.dat
are about 393 MB. Here I have two questions:</FONT></DIV>
<DIV><FONT color=#000080></FONT> </DIV>
<DIV><FONT color=#000080>1) What is the content inside the
LDDMMMatrix.dat?</FONT></DIV>
<DIV><FONT color=#000080>2) How to use the LDDMMmatrix.dat?</FONT></DIV>

DiffeoMap for 3D registration. I have done markers-based affine registration
