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

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 "grayordinates," which
represent the gray matter as cortical surface vertices (left and right) and
subcortical voxels (cerebellum, basal ganglia, and other deep gray matter).
'ciftiTools' provides a unified environment for reading, writing,
visualizing and manipulating CIFTI-format data. It supports the "dscalar,"
"dlabel," and "dtseries" intents. Grayordinate data is read in as a "xifti"
object, which is structured for convenient access to the data and metadata,
and includes support for surface geometry files to enable
spatially-dependent functionality such as static or interactive
visualizations and smoothing.
