.SH SYNOPSIS
.sp
\fBlandmark_warp [options]\fP
.SH DESCRIPTION
.sp
The landmark_warp executable performs registration by matching
fiducials on reference and test images.
The list of possible options can be seen by typing:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
landmark_warp \-\-help
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
The command line usage is given as follows:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
Usage: landmark_warp [options]
Options:
 \-a, \-\-algorithm <arg>         RBF warping algorithm {tps,gauss,
                                wendland}
 \-d, \-\-default\-value <arg>     Value to set for pixels with unknown

     \-\-dim <arg>               Size of output image
                                in voxels "x [y z]"
 \-F, \-\-fixed <arg>             Fixed image (match output size to this
                                image)
 \-f, \-\-fixed\-landmarks <arg>   Input fixed landmarks
 \-h, \-\-help                    Display this help message
 \-I, \-\-input\-image <arg>       Input image to warp
 \-v, \-\-input\-vf <arg>          Input vector field (applied prior to
                                landmark warping)

     \-\-origin <arg>            Location of first image voxel
                                in mm "x y z"
 \-O, \-\-output\-image <arg>      Output warped image

Options "\-a", "\-r", "\-Y", "\-d" are set by default to:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
\-a=gauss          Gaussian RBFs with infinite support
\-r=50.0           Gaussian width 50 mm
\-Y=0.0            No regularization of vector field
\-d=\-1000          Air

You may want to choose different algorithm:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
\-a=tps            Thin\-plate splines (for global registration)
\-a=wendland       Wendland RBFs with compact support (for
                   local registration)
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
In the case of Wendland RBFs "\-r" option sets the radius of support.
.sp
Regularization of vector field is available for "gauss"  and "wendland" algorithms. To regularize the output vector field increase "\-Y" to \(aq0.1\(aq and up with increment \(aq0.1\(aq.
