|---|---|
| other.files | Files to be written using the estimated normalization |
| bounding_box | matrix (2x3) of the bounding box to use. Default is for MNI 2mm template size |
| biasreg | Amount of bias regularization |
| biasfwhm | FWHM of Gaussian smoothness of bias. |
| regularization | parameters for warping regularization |
| affine | Space to register the image to, using an affine registration |
| smoothness | FWHM of smoothing done |
| sampling_distance | smoothingess of the warping field. This is used to derive a fudge factor to account for correlations between neighbouring voxels. Smoother data have more |
| voxel_size | The voxel sizes (x, y & z, in mm) of the written normalised images. |
| interp | Interpolator for sampling in fixed space |
| add_spm_dir | Add SPM12 directory from this package |
| spmdir | SPM dir to add, will use package default directory |
| clean | Remove scripts from temporary directory after running |
| verbose | Print diagnostic messages |
| install_dir | directory to download SPM12 |
