<br>When I run DemonsRegistration using the options as given in the command line below, I can get a few output files like final image, deformation field etc. How would I get the rest of the output like "True field file"? <br>As the image was not deforming enough, I had opted to reduce sigma from the default value of 1.5 to 0.8.. is this the correct approach?<br>Size of the fixed and moving images are 384x384x64 pixels each. I would like to register using the multi-resolution approach starting with 1/4th number of pixels in all 3 axes (i.e, 96x96x16), going to 1/2 (ie., 192x192x32 pixels) and finally to the full image. How will I do this?<br><br>Command:<br>>DemonsRegistration.exe -f CBCT1.mha -m CBCT4.mha -o Final.mha -O DefFld.mha -s 0.8 -d 1<br><br>Starting demons registration with the following arguments:<br>Arguments structure:<br> Fixed image file: CBCT1.mha<br> Moving image file: CBCT4.mha<br> Input field file:<br> Input transform file:<br> Output image file: Final.mha<br> Output field file: DefFld.mha<br> True field file:<br> Number of multiresolution levels: 3<br> Number of demons iterations: [ 15 10 5 ]<br> Deformation field sigma: 0.8<br> Update field sigma: 0<br> Maximum update step length: 2<br> Update rule: exponentialize and compose (Diffeomorphic)<br> Type of gradient: symmetrized (ESM for diffeomorphic and compositive)<br> Use histogram matching: false<br> Algorithm verbosity (debug level): 1<br><br>Thanks,<br>Ganesh<br><br><font style="" color="#1f497d" face="Verdana">************************************************************************</font><font style="" color="#1f497d" face="Verdana"><br></font><font style="" color="#1f497d" face="Verdana">
