Smooths metric GIFTI data along the cortical surface. The results are written to a new GIFTI file.

The GIFTI file to smooth.
Where to save the smoothed file.
Surface GIFTI files cortical surface along which to smooth. If not provided, the default inflated surfaces will be used.
The full width at half maximum (FWHM) parameter
for the gaussian surface smoothing kernel, in mm. Default: 5
The cortex hemisphere: "left" or "right".
Only used if surf_fname is NULL.
The ROI to limit smoothing to, as a metric file. This is used to exclude the medial wall from smoothing. If not provided (default) all the data is smoothed across the surface.
Should zero-values be treated as NA? Default: FALSE.
The smoothed GIFTI file name, invisibly
This function interfaces with the "-metric-smoothing" Workbench command.
