evaluate_field
evaluate a compact spline field representation and write it as a MINC volume
evaluate_field [options] -like <volume.mnc> <infile.fld> <outfile.mnc>
DESCRIPTION
evaluate_field evaluates a compact field representation (produced by spline_smooth) on a volume grid and writes the result as a MINC volume. The -like option specifies a reference volume whose sampling grid defines the output dimensions. This tool is used as part of the N3 non-uniformity correction pipeline to convert compact spline representations of the bias field into full MINC volumes.
OPTIONS
-clobber- Overwrite an existing output file.
-noclobber- Do not overwrite an existing output file (default).
-verbose- Print progress information (default).
-quiet- Do not print progress information.
-like <volume.mnc>- Specify the reference volume whose sampling grid the field is evaluated on.
-mask <mask.mnc>- Specify a mask volume defining the region on which the field is evaluated.
-byte- Write output with 8-bit integer voxels.
-short- Write output with 16-bit integer voxels.
-long- Write output with 32-bit integer voxels.
-float- Write output with 32-bit floating point voxels.
-double- Write output with 64-bit floating point voxels.
-signed- Write output with signed integer voxels.
-unsigned- Write output with unsigned integer voxels.
EXAMPLES
evaluate_field -like template.mnc field.fld output.mnc
evaluate_field -like template.mnc -mask brain_mask.mnc field.fld output.mnc
