nlfit_s
non-linear fitting at standard resolution step
nlfit_s <source.mnc> <target.mnc> <input.xfm> <output.xfm> [options]
DESCRIPTION
nlfit_s is a Perl wrapper script for performing non-linear registration using minctracc at a standard (medium) resolution step. It is part of the hierarchical nlfit suite that performs non-linear registration in a coarse-to-fine progression.
The standard resolution step uses an intermediate deformation grid spacing, capturing moderate anatomical differences between the source and target volumes. This step is typically run after the large resolution step (nlfit_l) and before the fine resolution step (nlfit_f).
The script takes a source volume, a target volume, an initial transformation (typically the output from the large resolution step), and produces a refined non-linear transformation at standard resolution.
OPTIONS
Options are passed through to minctracc. Common options include:
-verbose- Print progress information during fitting.
-clobber- Overwrite existing output files.
<source.mnc>- Source MINC volume to be registered.
<target.mnc>- Target MINC volume to register to.
<input.xfm>- Input transformation file from the large resolution step.
<output.xfm>- Output non-linear transformation file at standard resolution.
EXAMPLES
Run standard-resolution non-linear fitting after large step:
nlfit_s source.mnc target.mnc nlfit_l_output.xfm nlfit_s_output.xfm
