nlfit_f
non-linear fitting at fine resolution step
nlfit_f <source.mnc> <target.mnc> <input.xfm> <output.xfm> [options]
DESCRIPTION
nlfit_f is a Perl wrapper script for performing non-linear registration using minctracc at a fine resolution step. It is part of the hierarchical nlfit suite that performs non-linear registration in a coarse-to-fine progression.
The fine resolution step operates at the smallest deformation grid spacing, capturing detailed local anatomical differences between the source and target volumes. This step is typically run after the large (nlfit_l) and standard (nlfit_s) resolution steps have already established a coarse deformation field.
The script takes a source volume, a target volume, an initial transformation (typically the output from a previous coarser step), and produces a refined non-linear transformation at fine 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 a previous registration step.
<output.xfm>- Output refined non-linear transformation file.
EXAMPLES
Run fine-resolution non-linear fitting after standard step:
nlfit_f source.mnc target.mnc nlfit_s_output.xfm nlfit_f_output.xfm
