write_spheres

File path to left-hemisphere spherical GIFTI to be 
created

sphereL_fname

File path to right-hemisphere spherical GIFTI to be 
created

sphereR_fname

Target resolution for resampling (number of 
cortical surface vertices per hemisphere).

resamp_res

(Optional) directory to place the sphere files in. If
<code>NULL</code> (default), do not append any directory to the sphere file paths.

write_dir

(Optional) Path to Connectome Workbench folder or executable. 
If not provided, should be set with 
<code>ciftiTools.setOption("wb_path", "path/to/workbench")</code>.

wb_path

This function generates a pair of GIFTI vertex-matched left and right spheres
 in the target resolution. These are required for resampling CIFTI and GIFTI 
 files.

internal

CIFTI files contain brain imaging data in "gray-ordinates", which
represent the gray matter as cortical surface vertices (left and right) and
subcortical voxels (cerebellum, basal ganglia, and other deep gray matter).
'ciftiTools' uses the Connectome Workbench to read CIFTI files into R and
apply common pre-processing steps (e.g. smoothing, resampling). It also
provides tools for visualizing the cortical surface with GIFTI files, and
for visualizing the subcortical volume.
