If two surfaces are provided, then the dataset is filled between corresponding nodes. The filling is done by smoothing the holes with a local non-zero mean (or mode) in a spherical neighborhood. Holes come about because the lines from surfaces can miss some voxels. These are more likely with sparse surfaces, but can still happen even with high-resolution surfaces. Required (mostly) options: -maskset mymask.nii mask dataset in which to project surface measures -spec mysurfs.spec Surface specification file with list of surfaces -surfA mysurf1 nameof first surface, e.g. smoothwm, pial,.... -surfB mysurf2 name of second surface. If not included, computes using normal vector -surfset data.niml.dset dataset of surface measures -prefix mmmm basename of output. Final name used is prefix.nii.gz Other options: -f_pn_mm mm.m normal vector length if only using a single surface (default 2 mm) (only applies if no surfB used) -meanrad mm.m radius for search for mean to fill holes (default 2 mm) -nsteps nn number of steps on line segments (default 10) -keep_temp_files do not remove any of the temporary files (default is to remove them) -maxiters nn maximum number of smoothing and filling iterations (default is 4) -mode use mode instead of non-zero median (appropriate for ROIs) -datum cccc set datum type to byte, short or float instead of maskset type. mode triggers -datum short -ignore_unknown_options ignore additional options that are not needed Example usage: @surf_to_vol_spackle -maskset leftmask_1mm.nii.gz -spec quick.spec \ -surfA anat.gii -surfset v2s_inout_max_smooth2mm.niml.dset \ -prefix vol_thick_ave -maxiters 10 See related scripts and programs:
