echo \# This batch file shows an example of how to call elastix.
echo \# Run \"elastix -help\" for more information.
echo \#
echo \# This example requires elastix to be in your PATH.
echo \#
echo \# Here we perform a registration by doing sequentially:
echo \# 1\) a rigid registration
echo \# 2\) a bspline registration
echo \# We write all output in the exampleoutput directory.
echo \#
mkdir exampleoutput
echo
echo "elastix -f exampleinput/fixed.mhd -m exampleinput/moving.mhd -out exampleoutput -p exampleinput/parameters_Rigid.txt -p exampleinput/parameters_BSpline.txt"
echo
elastix -f exampleinput/fixed.mhd -m exampleinput/moving.mhd -out exampleoutput -p exampleinput/parameters_Rigid.txt -p exampleinput/parameters_BSpline.txt
echo \# In the following way we may mask the input images,
echo \# to prevent background pixels to be taken into account:
echo \#
echo \# elastix -f exampleinput/fixed.mhd -m exampleinput/moving.mhd -fMask exampleinput/mask_fixed.mhd -mMask exampleinput/mask_moving.mhd -out exampleoutput -p exampleinput/parameters_Rigid.txt -p exampleinput/parameters_BSpline.txt
echo \#
echo \# See /exampleoutput/ for the results:
echo \# 1\) elastix.log = the logfile
echo \# 2\) result.0.mhd = the rigidly transformed result
echo \# 3\) result.1.mhd = the bspline transformed result
echo \# 4\) TransformParameters.0.txt = the found translation+rotations
echo \# 5\) TransformParameters.1.txt = the found bspline parameters
echo \#
echo \# You may compare result.1.mhd to the solution, which is located in
echo \# ./exampleinput: solution_deformedmovingimage.mhd
echo \#
echo \# After doing the registration, we could apply the found deformation
echo \# to the moving mask. In that case, it would be necessary to change
echo \# the FinalBSplineInterpolationOrder to 0 first \(see manual\) in the
echo \# TransformParameters.1.txt file.
echo \# Once that has been done, call transformix as follows:
echo \#
echo
echo \# transformix -in exampleinput/mask_moving.mhd -out exampleoutput -tp exampleoutput/TransformParameters.1.txt
echo
echo \#
echo \# The /exampleoutput/ would then contain the following results:
echo \# 6\) transformix.log = the logfile
echo \# 7\) result.mhd = the transformed mask
echo \#
echo \# Transformix can also be used to generate a deformation field,
echo \# or the \"jacobian determinant\" field \(which indicates the amount
echo \# of compression/expansion.
echo \#
echo \# In this example, we generate the jacobian determinant field:
echo \#
echo
echo "transformix -jac all -out exampleoutput -tp exampleoutput/TransformParameters.1.txt"
echo
transformix -jac all -out exampleoutput -tp exampleoutput/TransformParameters.1.txt
echo \#
echo \# The /exampleoutput/ directory now additionally contains:
echo \# 8\) transformix.log = the logfile
echo \# 9\) spatialJacobian.mhd = the jacobian determinant image
echo \#
echo \# Please consult the website, FAQ, and manual for more information.
echo \# type elastix --help or transformix --help for an overview
echo \# of the command line arguments.
echo \#
echo \# If you have any questions, please register for the elastix
echo \# user mailing-list and post your question to the community!
echo \# In that way you will also be kept informed on updates.
