make_model
create a model for use with mritotal
make_model <input.mnc> <output_base>
DESCRIPTION
make_model is a shell script that creates a multi-resolution model from a MINC volume for use with minctracc registration. The script generates blurred versions and gradient derivative volumes at multiple resolutions (blur levels), which are required by the hierarchical registration strategy used by minctracc and mritotal.
For each resolution step, make_model produces:
- A blurred version of the input volume (Gaussian smoothing)
- Gradient magnitude and directional derivative volumes
The output_base argument specifies the base filename for the generated model files. Multiple files will be created with suffixes indicating the blur level (e.g., _blur8.mnc, _blur4.mnc, _blur2.mnc) and derivative type.
OPTIONS
make_model does not accept option flags. Both arguments are positional.
<input.mnc>- Input MINC volume to use as the basis for the model.
<output_base>- Base filename for the output model files. Multiple files are created with resolution and derivative suffixes appended.
EXAMPLES
Create a registration model from a template volume:
make_model mni152_t1.mnc mni152_model
This creates files such as mni152_model_blur2.mnc, mni152_model_blur4.mnc, mni152_model_blur8.mnc, and their corresponding derivative volumes.
